At constant temperature, increasing pressure causes gas volume to decrease.  

A gas mixture has a total pressure of 1.20 atm. If nitrogen contributes 0.45 atm, what is the partial pressure of the remaining gas?

If a reaction absorbs heat, the surroundings experience a temperature decrease.

When calculating heat using q = m c ΔT, the temperature change must always be expressed in Kelvin.
