An ideal gas may be taken from one state to another state with a different pressure, volume, and temperature along several different paths. Quantities that will always be the same for this process, regardless of which path is taken, include which of the following? I. The change in internal energy of the gas II. The heat exchanged between the gas and its surroundings III. The work done by the gas

correct option: 1

Explanation:

As given in the question that gas are taken from one sate to another state through different paths and asking which quantity will always remains same.

1. internal energy of gas is not path dependent so internal energy will remains same it depend only on the initial and final point .

2. Heat and work are path dependent means its matter the gas is taken by which path. so option 2 and 3 are wrong.
