1. What is the difference between heat capacity, specific heat, and latent heat? 2. Explain what is physically meant by "Degrees of Freedom" and the "Equipartition Theorem".

1.

- Heat capacity is defined as the total amount of heat required to increase the temperature of a substance in 1°C.

- Specific heat is defined as the total amount of heat required to increase the temperature of a substance in 1°C per unit mass. Hence this property depends of the mass of the substance.

- Latent heat is the amount of energy absorbed or released by a substance in a phase change (physical change) without a change in temperature.

2.

- Degrees of freedom is the number of parameters that define the configuration of a system. For example, in a system with we want to know about the dynamic in the three dimension x,y,z and also about the rotation around a fixed axe we have four degrees of freedom.

- Equipartition theorem relates the temperature of a system with the average energy of the system (this average is taken for those degrees of freedom that appears quadratically).

I hope this is useful for you

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
