A sample of a gas has a pressure of #"0.370 atm"# at a temperature of #"5.00"^@"C"#. What will the pressure be if the temperature is lowered to #"0"^@"C"#?
The pressure at
Gay-Lussac's gas law will be used to solve this problem. It states that the pressure of a gas is directly proportional to its Kelvin temperature, as long as mass and volume are held constant. This means that if the volume increases, so does the temperature and vice-versa. The equation for this law is:
The given data has temperature in degrees Celsius, so it needs to be converted to Kelvins. This is done by adding
