Select the correct answer. a sealed bottle is full of air. the volume of the bottle is decreased, but the temperature remains constant. what other change occurs in the bottle? a. the air pressure will increase. b. the air pressure will decrease. c. the number of air molecules will increase. d. the number of air molecules will decrease.

The air pressure will increase

Explanation:

The bottle is sealed, therefor the number of molecules can't change. The air inside the bottle may be considered as an ideal gas, and these have a particular set of laws they must obey.

In this case the law that apllies is Boyle's Law, which states that at a constant temperature, the pressure P of a gas varies inversely with its volume V, or P.V = k, where k is a constant.

If the volume is decreasing, the pressure must increase.

d.) circle motion requires a force to give it a centripetal acceleration.
