Problem 1. (Temperature and thermal equilibrium) Temperature is an indicator of: a. Total energy of the molecules in the system b. The average kinetic energy of the molecules in the system c. The average potential energy of the molecules in the system d. The average energy required to break the bonds between the molecules Problem 2. (Temperature and thermal equilibrium) Thermal equilibrium between two objects implies: a. There is no net heat flow between them b. They have the same temperature c. They have the same internal energy d. Both a and b

The average kinetic energy of the molecules in the system

Explanation:

According to the kinetic theory of matter, the particles of a system are in constant motion and collide steadily with one another as well as with the walls of the container.

The average kinetic energy of these molecules in motion is referred to as the temperature of the body. Hence, temperature is a measure of the average kinetic energy of the molecules of a body.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
