Question

Ідеальний газ отримав 300 Дж теплоти і виконав при цьому роботу 120 Дж. На скільки збільшилася внутрішня енергія газу?Решите с Дано: Я сам путаюсь в расстановке ​

Answer 1

Ответ:

180 Дж

Объяснение:

Q=300 Дж    A=120 Дж    ΔU=?

===

ΔU=Q-A=300-120=180 Дж (получил 300 и потратил на работу 120, осталось 180 в запасе)

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

Answer 2

To solve this problem, we need to use the first law of thermodynamics, which 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.

Given: - Heat added to the gas (Q) = 300 J - Work done by the gas (W) = 120 J

We can use the formula: ΔU = Q - W, where ΔU is the change in internal energy.

Substituting the given values into the formula, we get: ΔU = 300 J - 120 J ΔU = 180 J

Therefore, the change in internal energy of the gas is 180 J.
