An ideal gas received an amount of heat equal to 300 J and performed work equal to 100 J. How has the internal energy of the gas changed?
To solve this problem, you need to remember the laws of thermodynamics, namely, the first: a change in the internal energy of a gas is possible only under the influence of external factors.
This law has the formula: Q = ΔU + A.
The amount of heat is equal to the sum of work and internal energy.
It follows from this that the internal energy ΔU = Q – A.
ΔU = 300 – 100 = 200.
Answer: 200 J is the internal energy of an ideal gas.
