The weird symbol is your coefficient of friction which has no units
Fn stands for normal force
Answer:
B. The gas must release heat to its surroundings.
Explanation:
Since the process is reversible , it must be slow . Since temperature is kept constant so the internal energy is constant , Since volume is decreased , pressure must be increased. Since work is done on the gas ( gas is compressed ) , so heat must be released by the gas so that its internal energy remains constant.
Answer:
False, it is chemical change
Explanation:
sorry it this is wrong
