Question

99POINTS!!!!!!!!!!!!!!!!

Why does entropy increase over time? Check all that apply. Heat engines are not 100 percent efficient. The natural tendency of systems is to break down, from order to disorder. All energy added to a system is used to do work. Unusable thermal energy is lost to the surroundings. Entropy is a measure of the order of a system.

Answer 2

choices are:

Heat engines are not 100 percent efficient - true.

The natural tendency of systems is to break down, from order to disorder -true.

All energy added to a system is used to do work - not true n not related to entropy increase.

Unusable thermal energy is lost to the surroundings - true.

Entropy is a measure of the order of a system - true but not related to entropy increase.

so ans are 1, 2 n 4
