conducted is the total area of the six surfaces of the box and the length of the conducting material is the thickness of the styrofoam. We assume that all of the heat conducted into the box goes into melting the ice, and none into raising the temperature

Heat
We showed that the average translational kinetic energy of the molecules
in an ideal gas was related to there temperature. Now let us consider how
temperature and internal energy are related.
Internal energy U is the energy associated with the m
* While the first law of thermodynamics states that energy is conserved, not all processes that conserve energy occur in nature. Example: A hot object is placed in thermal contact with a cold object, heat flows spontaneously from hot to cold. The reverse
- An ideal gas is a gas in which the constituent molecules do not interact
with each other. The only exception to this is when molecules collide,
then they act in the same way as would billiard balls.
Note: All gasses can be considered ideal at su ciently

3.1 Temperature
Temperature is commonly associated with how hot or cold an object "feels" when we touch it. While our senses provide us with qualitative indications of temperature, they are unreliable and often misleadi
