Determine the change in internal energy of a monatomic ideal gas that expands from an initial volume of 1.53 m3 to a final volume of 2.87 m3. during this process the pressure of the gas remains at a constant value of 1.82 105 pa.

Internal energy will be

Explanation:

We have given that initial volume

And final volume

Pressure

Now change in volume

We know that change in internal energy is given by

, here we know that

Work done

So

d. air pressure decreases as altitude increases.

the answer is a. hope this .
