What determines how much an air parcel will cool?

Answers

Answer 1

Answer: As long as the parcel is unsaturated (relative humidity < 100% or whenever the dew point temperature of the parcel less than the temperature of the parcel ), the rate of cooling is 10°C for every 1000 meters the parcel is lifted. As a rising parcel cools, its relative humidity increases.

What is the second ionization energy?

The energy needed to free the outermost, or least bound, an electron from an element's 1+ ion is known as the second ionization energy.

The second ionization energy of an element is usually greater than the first because positive charge more strongly attracts electrons than negative charge.

The chemical equation is the representation of the chemical reaction. The left side of the substance and compound is the reactant and the right side of the substance is the product.

explain how both hydrogen and carbon have achieved stability by bonding with each other to form methane ​

Answers

A carbon iota can bond with four other iotas and is just like the four-hole wheel, whereas an oxygen iota, which can bond only to two, is just like the two-hole wheel.

Each element tries to achieve stability by forming a noble gas configuration (2 or 8 valence electrons)

Carbon has 4 valence electrons, achieving stability requires 4 more electrons

Hydrogen has 1 valence electron, achieving stability requires 1 more electron

Carbon and hydrogen bond covalently by sharing their electrons so that they become stable (carbon binds 4 hydrogens) to form CH₄ (methane)

What is the minimum mass of water at 70.°C needed to dissolve 36 g KNO3?

Answers

This problem is providing the mass of potassium nitrate at 70. °C and asks for the amount of water necessary to completely dissolve it. At the end, the answer turns out to be 26 g of water.

Solubility

In chemistry, we define solubility as the maximum amount of solute one can dissolve is an specific amount of solvent, at a determined temperature, without getting any trace of precipitate.

In such a way, with a solubility chart, one can see that potassium nitrate has a solubility of about 138 g in 100 g of water at 70. °C, which means we can compute the amount of water dissolving 36 g of this salt with the following relationship:

(a) more dense (b) sinks below

Answers

Answer:

3. (a) more dense (b) sinks to the bottom

4. (a) less dense (b) rises above

Explanation:

To understand this, first you need to know what density is. Density is the quantity of mass per unit. If something is dense it has many molecules per unit of volume. If something is not so dense it has few molecules per unit of volume.

Cold water is close to becoming ice. In ice (solid), the molecules are compacted very tightly, therefore there are more molecules per unit of volume. This means that ice is very dense. In cold water, the molecules are close but not as close as in ice. This means that cold water is dense.

Hot water is close to becoming a water vapour. In water vapour (gas) the molecules are spaced very far apart and move around freely. They have lots of energy so they vibrate and move around a lot. There are less molecules per unit of volume in water vapour. This means that water vapour is not dense. In hot water, the molecules are not so far apart as the molecules in water vapour. This means that hot water is not so dense. But it is still considerably denser.

Salt water has two different types of molecules. The salt molecules like to cluster around the water molecules very close together. This makes salt water more dense than just plain water (freshwater).

How is atmospheric oxygen linked to the carbon cycle?.

Answers

An increase in burial of organic carbon in sediments results in more oxygen in the atmosphere and oceans.

Atmospheric oxygen is closely linked to the carbon cycle through the process of photosynthesis and respiration.

During photosynthesis, plants and other photosynthetic organisms use carbon dioxide (CO₂) from the atmosphere, along with sunlight and water, to produce glucose (C₆H₁₂O₆) and oxygen (O₂) as a byproduct. This process removes carbon dioxide from the atmosphere and releases oxygen, contributing to the oxygen content in the atmosphere.

On the other hand, during respiration, organisms, including plants, animals, and microorganisms, use oxygen from the atmosphere to break down glucose and release carbon dioxide as a waste product. This process releases carbon dioxide into the atmosphere and consumes oxygen.

Hence, the atmospheric oxygen is linked to the carbon cycle.

A. 0. 625 L B. 0. 876 L C. 1. 18 L D. 1. 25 L.

Answers

The ideal gas equation states that the volume is directly proportional to the moles and temperature but inversely to pressure. The volume required is 1.25 L.

What is the ideal gas equation?

An ideal gas is the hypothetical gas equation that depicts the relation of the temperature, pressure, volume and moles of the substance of the gas.  It is given as,

[tex]\rm PV = nRT[/tex]

Where,

The pressure of hydrogen gas (P) = 1 atm

The volume of hydrogen gas (V) = 35.2L

The temperature of hydrogen gas (T) = 298 K

Gas constant (R) = 0.0821 L. atm. per mol. per K

Substituting values in the equation,

[tex]\begin{aligned}\rm n &= \rm \dfrac{PV}{RT}\\\\&= \dfrac{35.2\times 1}{0.0821\times 298}\\\\&= 1.438\;\rm moles\end{aligned}[/tex]

The balanced chemical reaction can be shown as,

[tex]\rm 2HCl + Ca \rightarrow H_{2} + CaCl_{2}[/tex]

is the ability of a substance to reflect light a chemical property

Answers

Answer:

If it reflects all light, it looks white. Color can help identify a material and, while it is a physical property, it can be used together with chemical experiments when the experiments produce a known material with a specific color.

Explanation:

The ability to reflect light is the inherent and fundamental property of that substance.

What type of object reflects light?When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space. The light wave that is coming in is known as the incident wave, and the wave that is being reflected off of the surface is known as the reflected wave. As seen for the operation of a flashlight beam on a smooth, flat mirror, visible white light that is focused onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle.For visible light and all other wavelengths of the electromagnetic radiation spectrum, the angle of incidence is the same as the angle of reflection. This idea is frequently referred to as the Law of Reflection. It is significant to notice that because the light is not "bent" or refracted and is being reflected at all wavelengths equally, it is not broken up into its individual hues.  Practically all surfaces will reflect light to some extent, particularly smooth surfaces, like a glass mirror or polished metal, work best for doing so.

Define climate and weather. What is climate change? Why is it important to know about climate change?

Answers

Answer:

It's important that we understand how the climate is changing so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures.

Weather is the state of the atmosphere at any given time and place.

Climate is the long-term average of the weather in a given place

Weather refers to short-term atmospheric conditions while climate is the weather of a specific region averaged for a long period.

Due to various reasons like different types of pollution and industrialization today the average temperature of the earth has begun to rise as a result several consequences are being faced by humans, one of which is climate change.

As the average temperature of the earth has begun to rise due to heavy industrialization, this is known as global warming. As a consequence, We face climate change in the terms of glacier meltdowns, irregular rainfall, and so on.

It is important to know about climate change because, at this point, our generation can reduce its effects of it and save future generations of the earth from being destroyed. If the temperature of the earth continues to rise, soon the plant will become inhabitable, and the entire human species will get vanished from the planet.

So, it is important for the current generation to know about the climate change and take steps in accordance with it.
