A gas delivers 874 J of heat and then has 159 J of work done upon it. The change in internal energy of the gas is

Nesterboy [21]

The change in internal energy of this gas sample is equal to: c. 715 J.

<u>Given the following data:</u>

Quantity of heat = 874 J.

Work done = 159 J.

<h3>What is the First Law of Thermodynamics?</h3>

Mathematically, the the First Law of Thermodynamics is given by this formula:

$\Delta H = Q-W$

Where;

$\Delta H$ is the change in internal energy.

Q is the quantity of heat.

W is the work done.

Substituting the parameters into the formula, we have;

$\Delta H =874-159\\\\\Delta H = 715$

Change in internal energy (ΔH) = 715 Joules.
