6 what is true of two objects at the same temperature? a they have the same number of molecules b their molecules stop moving c their molecules move at the same average speed d heat transfer between the two objects stops

6 what is true of two objects at the same temperature? a they have the same number of molecules b their molecules stop moving c their molecules move at the same average speed d heat transfer between the two objects stops

Answer

Brief Explanations:

Temperature is a measure of the average kinetic energy of molecules. When two objects are at the same temperature, they are in thermal equilibrium, and there is no net heat transfer between them. The number of molecules is not related to temperature (A is wrong). Molecules are always in motion (B is wrong). Molecules' average speed depends on mass and temperature, and same - temperature doesn't mean same - mass and thus not necessarily same average speed (C is wrong).

Answer:

D. Heat transfer between the two objects stops
