Question

Two litres of Nitrogen (N2) gas is initially at
a pressure of 10 Pa. Find the quantity of
heat energy required to double its volume
isobarically

Answer 1

Dear Student,

● Answer -

Heat required = 0.02 J

● Explaination -

# Given -

V1 = 2 L = 2×10^-3

P = 10 Pa

# Solution -

Heat required for isobaric expasion of gas is given by -

W = P.∆V

W = P (V2 - V1)

W = P (2V1 - V1)

W = P × V1

Now substitute values,

W = 10 × 2×10^-3

W = 0.02 J

Hence, 0.02 J of heat is required to double volume of given gas.

Thanks dear...
