Question

If a monatomic ideal gas of volume 1 litre at N.T.P. is compressed adiabatically to half of its volume, find the work done on the gas. Also find the work done if the compression is isothermal. ($y=\frac{5}{3}$)

Answer 1

Answer:

W = -70J

Step-by-step explanation:

Work done during isothermal compression is

W = 2.3026 nRT log10 (V²/V¹)

n = number of moles = 1/22.4 ,

T = 273K, R = 8.314J mol^-1 K^-1

V²/V¹ = ½ = 0.5

W = 2.3026×8.314×273log10(0.5/22.4

or

W = -70J
