일반물리학 1 — The Kinetic Theory of Gases: Problem 57

57 Suppose 1.80 mol of an ideal gas is taken from a volume of $3.00 \text{ m}^3$ to a volume of $5.50 \text{ m}^3$ via an isothermal expansion at $30^\circ\text{C}$. (a) How much energy is transferred as heat during the process, and (b) is the transfer to or from the gas?
