Question

True or False 1-energy cannot be "used up" but exergy can be. it is because the energy conserved and it simply transfer its from one to another.
2- heat is a form of avaliable and reversible energy but work is not. True or False 1-energy cannot be "used up" but exergy can be. it is because the energy conserved and it simply transfer its from one to another.

Explanation / Answer

1-TRUE

Explanation: According to the first law of thermodynamics (conservation of energy principle) states that energy is a thermodynamic property, and that during an interaction, energy can change from one form to another but the total amount of energy remains constant.

Exergy is the energy that is available to be used. After the system and surroundings reach equilibrium, the exergy is zero.

2-TRUE

Explanation: Heat is a form of energy, while work is a method of transferring energy. It can be proven that work can be totally converted to heat, but heat cannot be 100% converted to work.
