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.
<h3>What is the First Law of Thermodynamics?</h3>
Mathematically, the the First Law of Thermodynamics is given by this formula:
Where;
is the change in internal energy.
- Q is the quantity of heat.
Substituting the parameters into the formula, we have;
Change in internal energy (ΔH) = 715 Joules.
