Question

Fill in the blanks when the air expands it

Answer 1

Answer:

✨Here is the Answer......❣️

Explanation:

☯︎less dense (lighter)....

Because each molecule uses more space for motion, the air expands and becomes less dense (lighter). In other words, the same number of air molecules occupy a larger space or the same sized space with increased air pressure. The opposite effect happens when air cools.

Answer 2

Answer:

becomes lighter is the right answer.

Air enlarges and loses density (lighter).

Explanation:

• The molecules that makeup air are continually moving. The molecules in the air begin to bounce and collide as it warms up, creating more space between each molecule.
• The air expands and becomes less dense because each molecule requires a greater amount of space for mobility (lighter).
• In other words, a larger space or a space of the same size with higher air pressure is occupied by the same amount of air molecules.
• The air gets hotter as molecules move more quickly. The molecules are separate as they heat up and move more quickly.
• As a result, air expands when heated and compresses when it is cooled, like most other things. The air is less dense than the surrounding material because there is more space between the molecules, which causes the heated air to float higher.
• Hot air balloons operate under this theory.
• The burner heats the air, which then expands and becomes less dense, lifting the balloon above the cooler, denser surrounding air.
