Physics 2007 JAMB Past Questions - Question 33: which of the following gas laws is equivalent to the work done

Correct Answer

C

Explanation

The gas law that is equivalent to the work done on a gas is known as the "First Law of Thermodynamics," which is often expressed in terms of energy and work as:

ΔU = Q - W

Where:
- ΔU represents the change in internal energy of the gas.
- Q represents the heat added to or removed from the gas.
- W represents the work done by or on the gas.

In the context of this equation, when work is done on a gas (W is positive), it means the internal energy of the gas is increasing, and when work is done by the gas (W is negative), the internal energy is decreasing. This equation describes the conservation of energy for a closed system, which includes the work done on or by the gas as one of its components.
