When 20.9 J was added as heat to a particular ideal gas, the volume of the gas changed from 50.0 cm3 to 100 cm3 while the pressure remained at 1.00 atm. (a) By how much did the internal energy of the gas change? If the quantity of gas present was 2.00 *10-3 mol, find (b) Cp and (c) CV.
A gas in a cylinder is held at a constant pressure of 2.20×105 Pa and is cooled and compressed from 1.90 m3 to 1.10 m3 . The internal energy of the gas decreases by 1.15×105 J.
a) Find the work done by the gas. Express your answer in joules
b)Find the amount of the heat that flowed into or out of the gas. Express your answer in joules to two significant figures.
c) State the direction (inward or outward) of the flow.
The temperature of 3.00 mol of a gas with CV = 6.00 cal/mol K is to be raised 50.0 K. If the process is at constant volume, what are (a) the energy transferred as heat Q, (b) the work W done by the gas, (c) the change Eint in internal energy of the gas, and (d) the change K in the total translational kinetic energy? If the process is at constant pressure, what are (e) Q, (f) W, (g) Eint, and (h) K? If the process is adiabatic, what are (i) Q, ( j) W, (k) Eint, and (l) K?
