Use your knowledge of chemical principles and kinetic-molecular theory to explain the following statements.
a.) A lit candle placed in a sealed jar will not burn for very long.
b.) A glass of water left out in air can completely vaporize, although thetemperature never comes close to the boiling point of water.
c.) The volume of a gas-filled balloon placed underwater at a constant temperature will decrease as its depth below the surface of the water is increased.
d.) As the temperature of a gas is decreased, the measured pressure of the gas becomes less than the pressure predicted by the ideal gas law.
