Question

4. При изобарном расширении аргона взятого при нормальном атмосферном давлении его внутренняя энергия увеличилась на 300 Дж. Определите изменение объема аргона. Ответ выразите в литрах.

Answer 1

Дано     ΔU=300 Дж       P=100 000 Па   ΔV- ?
ΔU=3*PΔV/2
ΔV=2*ΔU/3*P=2*300/300 000=0,002 м3=2 л - ответ

Answer 2

Calculation of Change in Volume of Argon

To determine the change in volume of argon during an isobaric expansion, we need to use the formula:

ΔV = ΔQ / P

Where: - ΔV is the change in volume - ΔQ is the change in internal energy - P is the pressure

In this case, the change in internal energy (ΔQ) is given as 300 J. However, the pressure (P) is not provided in the question. Therefore, we cannot calculate the change in volume without knowing the pressure.

Please provide the pressure (P) value in order to proceed with the calculation.
