Multiple Choice

As exemplified in Boyle's Law, if the volume of a gas is decreased, the pressure will

also decrease.

• True

• False

Multiple Choice

At constant pressure and moles of gas, if the

temperature of a gas increases, the volume will also

increase.

• True

• False

Multiple Choice

Which of the following correctly expresses the

relationship between temperature and volume (Charles's

Law)?

• $T\propto\frac{1}{V}$

• $T\propto V$

Multiple Choice

The volume of a gas at a pressure of 400 mm Hg

doubles, what will be the new pressure if the process

involves no temperature change and the container is closed (number of moles is fixed)?
