Answer:
the Power required is 300 W
Explanation:
We know that the definition of work is given by the following expresion:
the distance is 1.5 meters and the Force is equal to 1000 N.
Replacing this values in the work expresion
And the power is equal to the amount of work done in a given time, therefore we have:
Time in seconds
The change in internal energy of the gas is 
.
In fact, the 1st law of thermodynamics states that the change in internal energy of a system is equal to the amount of heat given to the system (Q) plus the work done on the system (W):
In this example, no work is done on the bottle so W=0, while the heat given to the system is
, so the change in internal energy of the gas is
