Question

A truck was carrying a substance in a tank. The molecules of that substance were moving away from each other. The truck parked overnight in a place where energy transferred out of the substance. In the morning, the substance was a gas. How were the molecules moving in the morning? Explain why the molecules were moving that way after energy was transferred out of them.

Answer 1

Answer:

After parking overnight, where energy transferred out of the substance, in the morning, the substance was a gas. Hence, the molecules were moving away from each other too

Answer 2

A truck was carrying a substance in a tank.

Explanation:

• In the question it has been mentioned that there was some gaseous substance and the molecules of that substance were moving away from each other when the truck was moving.
• The truck parked was at same place overnight where energy was removed out of the substance. In the morning, also the substance was a gas.
• This happened because of the energy available did not surpass the attraction level of the gas in the tank.
• The kinetic energy of the gaseous phase atoms is the highest and the state of the gas did not change as the energy provided was not enough to change the state of the substance.
