(Page 43) Dalton's Law states...

• that at a constant temperature the volume of a confined ideal gas varies inversely with its pressure.

• that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases

• that the density of an ideal gas at constant pressure varies inversely with the absolute temperature of the gas.

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change
