Question

При нагревании на 7 градусов внутренняя энергия одноатомного идеального газа увеличилась на 348,6 Дж.Определить число моль данного газа.

Answer 1

ΔU=(3/2)*v*R*ΔT

v=2*ΔU/(3*R*ΔT)=4 моль

ΔU=348.6     ΔT=7     R=8.31

Answer 2

Calculation of the Number of Moles of a Monoatomic Ideal Gas

To determine the number of moles of a monoatomic ideal gas, we can use the equation that relates the change in internal energy of the gas to the number of moles, the molar specific heat capacity, and the change in temperature.

The equation is as follows:

ΔU = nCΔT

Where: - ΔU is the change in internal energy of the gas - n is the number of moles of the gas - C is the molar specific heat capacity of the gas - ΔT is the change in temperature

In this case, we are given that the change in temperature (ΔT) is 7 degrees Celsius and the change in internal energy (ΔU) is 348.6 J.

To find the number of moles (n), we need to know the molar specific heat capacity (C) of the gas. Unfortunately, the specific gas is not specified in the question. Therefore, we cannot provide an exact answer without this information.

Please provide the molar specific heat capacity of the gas, and we will be able to calculate the number of moles for you.
