Question

When a gas expands isobarically, the product of the pressure and change of volume is equal to which one of these statements? A. the heat transferred into the gas B. the product of the pressure and the change in temperature C. the product of the temperature and the change in pressure D. the work done by the gas on its surroundings

Answer 1

Answer:

A option

Explanation:

This is because heat taken by gas during isobaric expansion is equal to amount of work done which is equal to pressure × change in volume

q = w = -Pext × ∆V

Answer 2

Answer:

C. the product of the temperature and the change in pressure
