Question: For an ideal gas, which equation relates the change in internal energy to heat and work?

Options:

  1. ΔU = Q + W
  2. ΔU = Q - W
  3. ΔU = W - Q
  4. ΔU = Q * W

Correct Answer: ΔU = Q - W

Solution: 

The first law of thermodynamics states that the change in internal energy (ΔU) is equal to the heat added to the system (Q) minus the work done by the system (W).

Questions & Step-by-Step Solutions

For an ideal gas, which equation relates the change in internal energy to heat and work?
  • Step 1: Understand that internal energy (ΔU) is the energy contained within a system.
  • Step 2: Recognize that heat (Q) is energy transferred into the system.
  • Step 3: Know that work (W) is energy transferred out of the system.
  • Step 4: Learn the first law of thermodynamics, which connects these concepts.
  • Step 5: The equation is ΔU = Q - W, meaning the change in internal energy equals heat added minus work done.
  • First Law of Thermodynamics – The principle that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.
