Bell Work

Three soda cans are placed into three different situations as shown below. Which soda can has particles with the highest kinetic energy and why? What does this do to the pressure inside the can?

pressure and volume
Pressure and Volume
  • Increase volume , decrease pressure
  • Decrease volume, increase pressure
  • Pressure and volume are inversely related
    • Cut volume in half and pressure doubles
combined gas law
Combined Gas Law
  • P = pressure
  • V = volume
  • n= moles
  • T = temperature
  • Subscript 1 = initial
  • Subscript 2 = final

Read the problem

  • What variables are we dealing with?
  • Cover (Cancel) out extra variables
  • Write down variables and givens
  • Plug-in and Solve

A gas is collected in a 242 mL container. The pressure of the gas in the container is measured and determined to be 87.6 kPa. What is the volume of this gas at 101.3 kPa? Assume the temperature is constant.

P2= 101.3 kPa

V2= ?

P1 = 87.6 kPa

V1= 242 mL

  • Cover (Cancel) out extra variables
  • Write down variables and givens
  • Plug-in and Solve

If 1.0 L of a gas at standard temperature and pressure is compressed to 0.473 L, what is the new pressure of the gas?

P2= ?

V2= 0.473 L

P1 = 1.00 atm

V1= 1.0 L
