1.	one litre of hydrogen at 127 degree Celsius and 10 ki 10269 10 Inverse Square pressure expand isothermally unit it volume is doubled find the pressure of the gas
Answer» Answer: The formula you will use for isothermic expansion is: Work(W) = 2.303 RT LOG(V2/V1) Let R = 8.3 J / mole-K (universal gas CONSTANT and V2/v1 = 2/1 = 2. Converting temperature to KELVINS: T = 127°C = 400K Work(W) = (2.3)(8.3)(400)log(2) W = 2.3 X 10^3 J To find the heat absorbed: 2.3 x 10^3 J/4.2 = 548 cal.

Answer»

Answer:

The formula you will use for isothermic expansion is:

Work(W) = 2.303 RT LOG(V2/V1)

Let R = 8.3 J / mole-K (universal gas CONSTANT and V2/v1 = 2/1 = 2.

Converting temperature to KELVINS:

T = 127°C = 400K

Work(W) = (2.3)(8.3)(400)log(2)

W = 2.3 X 10^3 J

To find the heat absorbed:

2.3 x 10^3 J/4.2 = 548 cal.
