45. The value of Cp is greater than C, for an ideal gases, because (a) They are just two different quantities with no relationship between them. (b) For Cp, a part of heat entering the system is used up by doing work on the environment, hence more heat is needed to cause increase of temperature. (c) For Cv, gas molecules have a smaller kinetic energy since volume is constant, therefore less heat is required to cause an increase in their temperature. (d) For Cv, volume is constant, so less heat will leak out from the system, and therefore less heat is required to increase gas's temperature.

In a two-step process, heat is allowed to flow out of an ideal gas at a constant volume so that its pressure drops from 2.2 atm to 1.4 atm. Then the gas expands at constant pressure from a volume of 5.9L to 9.3L. In going from point (a) to point (c) : a) Is the gas hotter, colder, or the same temperature at point (c) as at the beginning (a)? (Hint: consider the ideal gas law.) b)what is the total work done by the gas in the process? c) what is the total heat flow and is it into or out of the gas? d) What is the change in the internal energy of the gas?
(1) A given mass of gas is enclosed in a suitable container so that it can be maintained at constant volume. Under these conditions, there can be no change in what property of the gas? (a) Pressure. (b) Density. (c) Internal energy. (d) Temperature. (e) None of the above.
2 (Thermodynamic Process) Figure 1 shows a PV diagram for n = 0.081 kmol of Helium gas, initially at 27°C and at pressure 2 x 105 N/m², taken over the path A → B → C. (For He C₂, = R, and Cp = R.)
(a) How many molecules are present in a sample of an ideal gas that occupies a volume of 1.90 cm3, is at a temperature of 20°C, and is at atmospheric pressure? molecules (b) How many molecules of the gas are present if the volume and temperature are the same as in part (a), but the pressure is now 1.80 ✕ 10−11 Pa (an extremely good vacuum)? molecules
Hi please help: a bubble with original volume 2.5 cm^3 rises from the bottom of a lake to the surface where it grows to a volume of 5.9cm^3 at a pressure of 1.0 atm. Gas molecules were absorbed by the water as the bubble rose so that only 82% of the original gas is in the 5.9 cm^3 bubble at the surface. The temperature at the bottom is 8.2 degrees Celsius and the temperature at the surface is 23.4 degrees Celsius. Find the pressure at the bottom of the lake (in atm). Use 3 significant figures

The increase in internal energy is ............. for one mole of water under a pressure of 1013 N/m2 and a temperature of 273 K when it turns into steam under the same temperature and pressure, knowing that the amount of heat needed to evaporate water is 40680 J and that the molar volume of an ideal gas is 0.0224 cm3 and for water it is 18 10-6 cm3. *
An insulated container contains two moles of an ideal gas at atmospheric pressure. Keeping the pressure constant, if the temperature of the gas is increased by 50 °C, then its volume increases by 400 cm3 and if the temperature is increased by 100 °C, then its volume increases by 600 cm³. Determine the initial volume and temperature of the gas. (Write the equation of ideal gas initially, after the temperature increase of 50 °C, and after increase of temperature by 100 °C. Combine these three equations to find the initial volume and temperature)

4- A mass of gas at an initial pressure of 30 bar, and with an internal energy of 1500 kJ, is contained in a well-insulated cylinder of volume 0.1 m'. The gas is allowed to expand behind a piston until its internal energy is 1300 kJ; the law of expansion is pv = constant. Calculate: a- the work done; b- the final volume; c- the final pressure.
