Unformatted text preview: ses, the frequency of
collisions with the walls of the container must increase.
• This, in turn, leads to an increase in the pressure of the gas.
• Flexible containers, such as a balloon, will expand until the
pressure of the gas inside the balloon once again balances the
pressure of the gas outside.
• Thus, the volume of the gas is proportional to the number of gas
particles. The Gas Laws
• Charles Law – The volume of a gas increased with the temperature
– The volume of a given amount of dry ideal gas is directly
proportional to the Kelvin Temperature provided the amount
of gas and the pressure remain fixed.
– When we plot the Volume of a gas against the Kelvin
temperature it forms a straight line.
– V1 / T1 = V2 / T2 • Boyle’s Law – the product of the pressure and volume are observed to be
nearly constant.
– The product of pressure and volume is exactly a constant for
an ideal gas.
– p * V = constant WATER VAPOR (9.8oC)...
