A cylinder is in thermal equilibrium with the gas that it contains. The cylinder is then placed in a water bath. If the temperature of the water is observed to increase, which of the following statements is correct regarding the gas and the cylinder?

  (A) Q<0 , W=0, and U<0

     (B) Q>0 , W<0, and U=0

     (C) Q<0 , W>0, and U=0

     (D) Q>0 , W=0, and U>0

     (E) Q=0 , W<0, and U<0

Homework Answers

Answer #1

Option (A) is correct, Because here heat is lost to the water   Q 0 ( negative i. e heat is decreasing )

*Volume of gas in cylinder remain constant

i. e V=0

W= 0

* since heat is released by cylinder so internal energy is decreasing U0

A mixture of gases A2 and B2 are introduced to a slender metal cylinder that has one end closed and the other fitted with a piston that makes a gas-tight seal so that the gases are a closed system. The cylinder is submerged in a large beaker of water whose temperature is 25 °C, and a spark is used to trigger a re-action in the cylinder. At the completion of the reaction, the piston has moved downward, and the temperature...

A cylinder contains 0.200 mol of carbon dioxide (CO2) gas at a temperature of 30.0 ∘C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The cylinder is placed on a hot plate and a 920 J of heat flows into the gas, thereby raising its temperature to 124 ∘C. Assume that the CO2 may be treated as an ideal gas. What is the change in internal energy of the...
