Suppose the internal energy of an ideal gas rises by 2.89 103 j at a constant pressure of 1.00 105 pa, while the system gains 6.44 103 j of energy by heat. find the change in volume of the system.

Explanation:

According to the first law of thermodynamics:-

Where,  

U is the internal energy  =

q is the heat  = (heat is gained)

w is the work done  = ?

The expression for the calculation of work done is shown below as:

Where, P is the pressure,  

is the change in volume

Also, 1 J = 1000 PaL

So,

From the question,
