Q1
For an ideal gas, which equation relates the change in internal energy to heat and work?
ΔU = Q + W
ΔU = Q - W
ΔU = W - Q
ΔU = Q * 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.
