Answer: C) Increase the amplitude of the wavelenghth to increase the intensity.
Explanation:
You have a small container of solid ice water, H2O, currently in A on the graph. You choose to increase the amount of thermal energy in the system in two steps. In step 1, you add energy so that it goes to B. In step 2, you add energy so that it goes to C. Which choice most accurately describes what you will observe?
(A) In Step 1, you will observe the temperature of the solid water will increase until it gets to B. While in B, the temperature will continue to increase and the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will remain constant while it’s in C.
(B) In Step 1, you will observe the temperature of the solid water will increase until it gets to B. While in B, the temperature will continue to increase and the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will increase if the energy increases while it’s in C.
(C) In Step 1, you will observe the temperature of the solid water will increase until it gets to B. While in B, the temperature will remain constant but the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will increase if the energy increases while it’s in C.
(D) In Step 1, you will observe the temperature of the solid water will remain constant until it gets to B. While in B, the temperature will increase and the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will increase if the energy increases while it’s in C.
Answer:
"In Step 1, you will observe the temperature of the solid water will increase until it gets to B. While in B, the temperature will remain constant but the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will increase if the energy increases while it’s in C."
Explanation:
As per the details given, In Step 1, you will observe the temperature of the solid water will increase until it gets to B. While in B, the temperature will remain constant but the solid water will start melting into liquid water. The correct option is C.
The temperature of solid ice rises as a result of thermal energy absorption until it approaches the melting point (B on the graph).
As the ice turns to liquid water at this moment, the temperature stays the same.
Because the energy is being utilised to break the intermolecular bonds holding the solid structure together rather than increasing the kinetic energy (temperature) of the particles, this phase transition doesn't involve a change in temperature.
Once all of the ice has melted and turned into liquid water (point C on the graph), adding more thermal energy will in fact raise the temperature of the liquid water, increasing both temperature and kinetic energy.
Thus, the correct option is C.

O Both can transfer energy through empty space.
O Both transfer thermal energy by electromagnetic waves.
O Both involve the transfer of energy through direct contact,
Please help me
Answer:
Both transfers thermal energy from warm objects to cooler objects
Explanation:
Both transfer thermal energy from warm objects to cooler objects
B. Write True if the statement is correct, False if otherwise
6. When matter solidifies, it turns directly to solid state without passing through the liquid state
7. The particles of an object vibrate slower when it absorbs energy.
8. When the kinetic energy increases, the particles of matter vibrate faster.
9. During evaporation, matter releases energy and loses kinetic energy
10. Freezing occurs when matter absorbs energy.
11. Condensation happens when gaseous matter turns to its liquid state
12. When matter sublimes, it releases energy and turns to gas easily without passing through the liquid state.
13. During deposition and condensation, matter releases energy.
14. Melting is the opposite of freezing.
15. During evaporation and melting, the kinetic energy of the particles of matter increases.
Answer:
6.False
Explanation:
When matter solidifies it first go through liquid state before it becomes solid so the answer is false it does not directly turn into solid state without passing through liquid state
Particles of an object will vibrate faster when it absorbs energy.
Freezing does not occurs when matter absorbs energy.
So, all except 7 and 10 are true.
What is meant by energy ?Energy is defined as the ability to do work. Energy can be of various types such as kinetic energy, potential energy, electrical energy, thermal energy and various other types.
Here,
6. When matter solidifies, it turns directly to solid state without passing through the liquid state.
This is true because this transformation is done through the process called deposition in which the matter gets a phase change from gaseous state to solid state directly without passing through liquid state.
7. The particles of an object will not vibrate slower when it absorbs energy. This is because, the more amount of energy it absorbs will make them more faster that they vibrates with more speed.
So, the statement is false.
8. When the kinetic energy increases, the particles of matter vibrates faster. This is because, as the kinetic energy increases, it allows the molecules to move more freely and thus the rate of diffusion gets increased. This makes the particles to vibrate faster.
9. During evaporation, matter releases energy and loses kinetic energy. This is because, during evaporation, the molecules tend to escape from the liquid surface so that it moves faster and attains the threshold energy. As a result, the average kinetic energy decreases. So, the statement is true.
10. Freezing does not occurs when matter absorbs energy because, when matter absorbs energy, the intermolecular force of attraction between the molecules decreases and the matter starts diffusing which is the opposite mechanism of freezing. So, the statement is false.
11. Condensation is the process of conversion of vapour or gas into liquid state. So, the statement is true.
12. Sublimation is the process of conversion of solid matter into gaseous state directly without passing through liquid state. So, the statement is true.
13. During deposition and condensation, the gaseous matter releases energy and the random motion of the molecules decreases. So, the statement is true.
14. Melting is the process of conversion of solid matter into liquid state, which is the opposite mechanism of freezing. So, the statement is true.
15. During evaporation and melting, the kinetic energy of the particles increases and the molecules move more randomly and faster. So, the statement is true.
Hence,
Particles of an object will vibrate faster when it absorbs energy.
Freezing does not occurs when matter absorbs energy.
So, all except 7 and 10 are true.

The box accelerates at 1. 0 m/s² to the right because the net force is 17N to the right . This statement clearly depicts the relation between force and acceleration. Hence option A is correct.
What is acceleration?
Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec².It is a vector quantity. It requires both magnitudes as well as direction to define.
According to Newton's second law of motion, the net force acting on the body is equal to the product of mass and acceleration of the body.
The direction of acceleration is in the direction of net force acted.
