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.

the answer is alpha particles hope i you

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
