1 atm

Question 16

______ _____ is the pressure exerted by a column of air from the top of the atmosphere to the surface of earth. It decreases as altitude increases (1atm at sea level)

Answer 16

Atmospheric pressure.

Question 17

The inverse relationship between the pressure and volume of a gas is ____ law

Answer 17

Boyle’s

Question 18

What is Boyle’s law?

Answer 18

The inverse relationship between the pressure and vol. p1v1=p2v2

Question 19

When _____ increases, the pressure decreases. (if the temperature and moles of gas remain constant)

Answer 19

Volume

Question 20

Volume _______ as pressure______

Answer 20

volume increases as pressure decreases

Question 21

What is Charle’s Law?

Answer 21

If the amount and pressure of the gas is held constant, the volume of the container will increase with an increase in temperature (v1/T1 = v2/T2)
