Question

A vessel containing Vi m’ of an ideal
gas initially at P Pa pressure is
connected to an evacuated vessel of
V2 m. There is no change in
temperature. The final pressure is nearly
A
PV
(Vi+V2)
B
2PV
(V1 +V2)
с
PV2
(V1 +V2)
D
2PV2
(V1 +V2)​

Answer 1

Answer:

P = W / t. The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second.
