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.
