A given gas occupies 10.0L and exerts a pressure of .5 atm. When the temperature of the gas rises by 45K, the new volume and pressure are 10.2L and .8 atm.
(1) What was the original temperature of the gas?
The amount of the gas does not change with the increase in temperature. In addition, the ideal gas constant always has the same value. Therefore the ideal gas law gives
