The pressure, measured in Pascals (abbreviated Pa) on a certain object B is proportional to the temperature measured in degrees Kelvin (degK), and inversely proportional to the volume of B in cubic meters:
where is a physical constant that depends on B and converts the units to Pascals. In this problem it is
Suppose the temperature and the volume both depend on time, hence so the does the pressure: . At time seconds the temperature of B is and is increasing at a rate of , and the volume is and is increasing at the rate .

Using the quotient rule, the pressure on the object is changing at the rate
Your answer should include units.
