Gas Laws Pressure and Volume

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?

Presentations about 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 P = pressure V = volume n = moles T = temperature Subscript 1 = initial Subscript 2 = final

The pressure of the gas in the container is measured and determined to be 87. 6 k. Pa. What is the volume of this gas at 101. 3 k. Pa? Assume the temperature is constant. P 1 = 87. 6 k. Pa V 1 = 242 m. L P 2 = 101. 3 k. Pa V 2 = ?
