Question

Яку роботу виконуе азот массою 56 кг пид час изобарного нагривання на 10 градусив

Answer 1

A=p*dV=m*R*dT=56*8,31*10=4653,6 Дж

Answer 2

Calculation of Work Done during Isobaric Heating

To calculate the work done during isobaric heating, we can use the formula:

Work = Pressure x Change in Volume

Given: - Mass of the gas (m) = 56 kg - Change in temperature (ΔT) = 10 degrees

We need to find the pressure and the change in volume to calculate the work done.

Finding Pressure:

To find the pressure, we can use the ideal gas law equation:

PV = nRT

Where: - P = pressure - V = volume - n = number of moles - R = ideal gas constant - T = temperature

Since the mass of the gas is given, we can calculate the number of moles using the mass and molar mass of the gas.

Finding Change in Volume:

The change in volume can be calculated using the ideal gas law and the given change in temperature.

Calculation:

Let's calculate the pressure and change in volume using the given information and then find the work done during the isobaric heating.
