The general gas energy equation is (where Q1 - 2 = Heat supplied, dU = Change in internal energy, and W1 - 2 = Work done in heat units) Q1 - 2 = dU × W1 - 2 Q1 - 2 = dU/W1 - 2 Q1 - 2 = dU - W1 - 2 Q1 - 2 = dU + W1 - 2 TRUE ANSWER : ? YOUR ANSWER : ?
All perfect gases change in volume by 1/273th of its original volume at 0°C for every 1°C change in temperature, when the pressure remains constant. This statement is called Boyle's law Charles' law Gay-Lussac law Joule's law TRUE ANSWER : ? YOUR ANSWER : ?
