question 28

Multiple Choice

A cylinder containing an ideal gas has a volume of 3.0 m³ and a pressure of 1.0 × 10⁵ Pa at a temperature of 300 K.The cylinder is placed against a metal block that is maintained at 900 K,and the gas expands as the pressure remains constant until the temperature of the gas reaches 900 K.The change in internal energy of the gas is +6.0 × 10⁵ J.How much heat did the gas absorb?

• A) 0
• B) 6.0 × 10⁵ J
• C) 12 × 10⁵ J
• D) 9.0 × 10⁵ J
