Question

a gas occupies 2L at stp it is provided 300J of heat so that it volume becomes 2.5 L calculate the change in its internal energy​

Answer 1

Dear Student,

◆ Answer -

∆U = 249.33 J

● Explanation -

# Given -

V1 = 2 L

q = 300 J

V2 = 2.5 L

# Solution -

Change in internal energy is calculated by formula -

∆U = q - P∆V

Substitute values,

∆U = 300 - 1 × (2.5 - 2) × 101.33

∆U = 300 - 50.67

∆U = 249.33 J

Therefore, change in internal energy of the gas is 249.33 J.

Hope this helps you...
