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 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...

3,1 moles of an ideal gas with a molar heat capacity at constant volume of 5,1 cal/(mol∙K) and a molar heat capacity at constant pressure of 7,7 cal/(mol∙K) starts at 317,6 K and is heated at constant pressure to 335,9 K, then cooled at constant volume to its original temperature. How much heat (cal) flows into the gas during this two-step process? Answer in two decimal places.
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...
There is a cylinder which contains 1 mole of ideal gas which initial pressure, volume, temperature is A, B, D. If heat(q) is injected to this cylinder, the pressure of gas changed into sqrt(2)R*A, the volume of gas changed into 2.5B, and the temperature of gas changed into 5*sqrt(R)*D. Calculate the heat in terms of A, B, D. (Molar heat capacity Cv=2R).
