Question

1.) How will the rising of a hot air balloon in cold air be different then if it rises in warm air?

Answer 1

Answer:

a.)It will rise faster in cooler air

a.) heat

Explanation:

i

A hot air balloon rises faster if cold air were to surround it due to density differences between the air in the two medium.

• Hot air is less dense as the average kinetic energy of the molecules is greater.
• Cold air is denser.
• This density contrast causes the balloon to move up at a high pressure.

ii. Heat

The average kinetic energy of the molecules in a substance is termed heat.

Heat is a form of thermal energy measured by the kinetic energy possessed by molecules in a substance.
