Combined Gas Law: Combined Gas Law Worksheet 1 Answer Key
The combined gas law is a mathematical equation that relates the pressure, volume, and temperature of a gas. It is a combination of Boyle’s law, Charles’s law, and Gay-Lussac’s law.
Combined Gas Law Formula
The combined gas law formula is:
(P1V 1)/T 1= (P 2V 2)/T 2
where:
- P is the pressure of the gas in pascals (Pa)
- V is the volume of the gas in cubic meters (m 3)
- T is the temperature of the gas in kelvins (K)
- 1 and 2 refer to the initial and final states of the gas, respectively
Example, Combined gas law worksheet 1 answer key
A gas has a pressure of 100 kPa, a volume of 2 m 3, and a temperature of 298 K. If the pressure is increased to 200 kPa and the volume is decreased to 1 m 3, what is the new temperature of the gas?
Using the combined gas law formula:
(P1V 1)/T 1= (P 2V 2)/T 2
and substituting the given values:
(100 kPa x 2 m3)/298 K = (200 kPa x 1 m 3)/T 2
Solving for T 2:
T2= (200 kPa x 1 m 3x 298 K)/(100 kPa x 2 m 3) = 298 K
Therefore, the new temperature of the gas is 298 K.
