Interpretation: The average kinetic energy of the molecules in an ice bath and in a balloon is to be compared.
Concept introduction:
Kinetic energy is a type of energy that a moving object or particle possesses. Among, liquids, solids, and gases, gases possess the highest kinetic energy.
Answer to Problem 67A
The average kinetic energy of molecules will be the same.
Explanation of Solution
The relationship between kinetic energy and temperature is as follows:
Here,
Thus, from the above expression, kinetic energy is directly proportional to temperature.
Both the block of ice and a gas-filled weather balloon is at the same temperature, i.e.,
