Question

Получив какое-то количество теплоты, газ совершил работу на 100 кДж. При этом внутренняя энергия газа повысилась на 150 кДж. Какое количество теплоты получил газ?

Answer 1

Ответ:

250 кДж

Объяснение:

A=100 кДж    ΔU=150 кДж    Q=?

===

Q=ΔU+A=150+100=250 кДж

=========================

Answer 2

Ответ

250 кДж

Объяснение:

A=100 кДж    ΔU=150 кДж    Q=?

Q=ΔU+A=150+100=250 кДж

Answer 3

Calculation of Heat Received by the Gas

To calculate the amount of heat received by the gas, we need to consider the change in internal energy and the work done by the gas.

Given: - Work done by the gas = 100 kJ - Increase in internal energy of the gas = 150 kJ

The first law of thermodynamics states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.

Mathematically, this can be represented as:

ΔU = Q - W

Where: - ΔU is the change in internal energy - Q is the heat added to the system - W is the work done by the system

In this case, we have: - ΔU = 150 kJ - W = 100 kJ

Substituting these values into the equation, we can solve for Q:

150 kJ = Q - 100 kJ

Rearranging the equation to solve for Q:

Q = 150 kJ + 100 kJ

Q = 250 kJ

Therefore, the gas received 250 kJ of heat.
