What is the heat capacity at constant volume, Cv, of an ideal gas, in ??? ?? °? if the constant pressure heat capacity, Cp = 0.124 ?? ??? ? and the molar mass of the material is 28 ton/ton-mole?
The amount of heat needed to raise the temperature of 1 mole of a substance by one Celsius degree (or, equivalently, one kelvin) is called the molar heat capacity of the system, denoted by the letter C. If a small amount of heat dQ is put into n moles of a substance, and the resulting change in temperature for the system is dT, then C=1ndQdT. This is the definition of molar heat capacity--the amount of heat Q added per infinitesimal...
Find how the heat capacity CV varies with changing volume at constant temperature.
Find how the heat capacity CV varies with changing volume at constant temperature.
The molar heat capacity of an unknown gas at constant volume depends on its temperature as: Cv,m = 12.8 kJ moll.K1 +0.0091 kJ molK2xT What is the change in internal energy of 1 mol of this gas as its temperature increases from 278 K to 357 K? (The sign matters!)
The value of the heat capacity for a substance depends on whether it’s measured under constant pressure conditions or constant volume conditions. The constant-pressure molar heat capacity is given by = (dq/dT)P and the constant-volume heat capacity is given by = (dq/dT)V Note that we use d instead of because q is not a state function of temperature, volume, and pressure; its value depends on how we execute the process. Here are several questions regarding heat capacity. a. When we...

1. Acetone has a heat capacity at constant volume of 61.50 J/mol K at 310 K when it is in the gas phase. Consider the system where 1.500 moles of acetone is placed in an adiabatic chamber at 330.04 K. It is allowed to expand such that during the expansion the temperature drops to 288.05 K. Calculate the work done and the change in internal energy for the system. Assume the heat capacity is constant over this temperature range. (ANS:...
2. Consider a closed system with three possible energy values, O, E, and 2€, under constant V and T condition. The third energy level with E = 2€, however, has a degeneracy of y: i.e. There are states that have the identical energy value of 2€. (a) Express the partition function in terms of %, E, and T. (b) Write the probability to sample each energy level (P1, P2, and P3) in terms of 7, €, and T. (c) Write...
