Question
The temperature of the air in a basketball increases as it is pumped up.Which is true??
The total kinetic energy of the air is increasing and the average kinetic energy of each atom is decreasing.
The total kinetic energy of the air is increasing and the average kinetic energy of each atom is increasing.
The total kinetic energy of the air is decreasing and the average kinetic energy of each atom is decreasing.
The total kinetic energy of the air is decreasing and the average kinetic energy of each atom is increasing.
Explanation / Answer
The total kinetic energy of the air is increasing and the average kinetic energy of each atom is increasing. When temperature increases, molecules move faster (like when you boil water). Therefore, their kinetic energies increase which, in turn, increases the average KE of the system.
