The Combined Gas Law (5.1.4)

Question 1

• Boyle’s law states that the pressure of a gas times its volume is a constant;
Charles’s law states that the volume of a gas divided by its temperature in
kelvins is a constant.

Answer 1

• Boyle’s law states that the pressure of a gas times its volume is a constant;
Charles’s law states that the volume of a gas divided by its temperature in
kelvins is a constant.

Question 2

• The combined gas law states that the pressure of a gas times its volume and
divided by its temperature is a constant.

Answer 2

• The combined gas law states that the pressure of a gas times its volume and
divided by its temperature is a constant.

Question 3

Boyle’s law states that the pressure of a gas times
its volume is a constant at constant temperature
(PV = constant).
Charles’s law states that the volume of a gas
divided by its Kelvin temperature is a constant at
constant pressure (V/T = constant).
The combined gas law is a combination of Boyle’s
law and Charles’s law. The combined gas law
states that the pressure of a gas times its volume
and divided by it temperature is a constant.
A 2.37 L sample of gas at 25.0˚C and 1.00 atm is
heated to 297.0˚C and simultaneously compressed
to a pressure of 10.0 atm. What is the final volume?
First, convert the temperatures to kelvins by adding
273.15. Plugging the known values into the
combined gas law yields the final volume, 0.453 L.
