Answer: The power is a measure of the rate at which work is done (or similarly, at which energy is transferred). The standard unit of power is Watt (1W). The power is determined by the change in energy, delta E (number of joules) and delta t, which is the time taken in seconds then: P= delta E/ delta t.

Explanation:
Magnitude of acceleration = (change of speed) / (time for the change)
Change of speed = (speed at the end) - (speed at the start)
Change of speed = (18 m/s) - (0 m/s) = 18 m/s
Time for the change = 22 sec
Magnitude of acceleration = (18 m/s) / (22 sec)
<em>Magnitude of acceleration = 0.818 m/s²</em>

ASSUMING that the substance is a gas . . .
It all depends on HOW the pressure was increased.
-- IF the gas was left in the same container, and the pressure was increased by heating the container, then the volume hasn't changed. It's still the inside volume of the container.
-- IF the pressure was increased by stuffing all of the gas into a smaller container, then the new volume is the volume of the smaller container.
No matter what the mass or temperature of the gas is, it always expands to fill whatever container you're keeping it in.
