Question

В цилиндре под поршнем находится 1,25 кг воздуха. Для его нагревания на 4 градуса Цельсия при постоянном давлении было затрачено 5 кДж теплоты. Определите изменение внутренней энергии воздуха(М=0,029кг/моль).

Answer 1

Там может в ответе получится и 3569 Дж, а не 3568 Дж

Т.к. когда делишь 1,25 на 0,029 то получается 43,10344827586207

 

Answer 2

Calculation of Change in Internal Energy of Air

To calculate the change in internal energy of the air, we can use the equation:

ΔU = m * C * ΔT

Where: - ΔU is the change in internal energy - m is the mass of the air - C is the specific heat capacity of air at constant pressure - ΔT is the change in temperature

Given: - Mass of air, m = 1.25 kg - Change in temperature, ΔT = 4 °C - Specific heat capacity of air at constant pressure, C = ? (to be determined)

We need to find the specific heat capacity of air at constant pressure, C, in order to calculate the change in internal energy.

Unfortunately, the specific heat capacity of air at constant pressure is not provided in the given information or search results. Therefore, we cannot determine the exact change in internal energy of the air without this information.
