Practicing Success
An ideal gas is filled in a closed rigid and thermally insulated container . A coil of 100 Ω resistor carrying a current of 1 A for 5 minutes supplies heat to the gas . What is the change in the internal energy of the gas? |
50 kJ 30 kJ 15 kJ 10 kJ |
30 kJ |
heat supplied = the change in internal energy = I2Rt |
