A piston-cylinder assembly contains 0.3 lb of propane. The propane expands from an initial state where p₁ = 60 lbf/in.² and T₁ = 90°F to a final state where p2 = 10 lbf/in.² During the process, the pressure and specific volume are related by pv² = constant. Determine the energy transfer by work, in Btu. W= MI Btu

The formula v = √(P/ρ) can be used for any gas considering isothermal process. True or False? a) True b) False

The temperature of 10 moles of an ideal gas is 1000 K. Compute the work done by the gas when it expands isothermally to three times its initial volume.  Given:    Boltzmann constant: k = 1.38 x 10–23 J/K,      Ideal Gas Constant: R = 8.31 J/(mol K) A. 91300  J B. 9130 J C. 913 J D. 91 J E. 9 J

An ideal gas expands isothermally, performing 5.00×103 J of work in the process.  Part A Calculate the change in internal energy of the gas. Part B Calculate the heat absorbed during this expansion.

QUESTION 16 The temperature at state A is 20.0°C, that is 293 K. During the last test, you have found the temperature at state D is 73.0 K and n = 164 moles for this monatomic ideal gas. What is the change in thermal energy for process A to D, in MJ (MegaJoules)? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. p (atm) 5 4 3 2 1 0 A D 1 2 3 4 B 5 → V (m³)
