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

Given the following data:

  • Quantity of heat = 874 J.
  • Work done = 159 J.

What is the First Law of Thermodynamics?

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

[tex]\Delta H = Q-W[/tex]

Where;

  • [tex]\Delta H[/tex] 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;

[tex]\Delta H =874-159\\\\\Delta H = 715[/tex]

Change in internal energy (ΔH) = 715 Joules.
