Homework: Thermodynamic Processes And The First Law Deadline: 100% until Wednesday, January 31 at 11:00 PM Problem 18 The temperature of 4.00 g of helium gas is increased at constant volume by 1.00 C. 1) Using the same amount of heat, the temperature of what mass of hydrogen gas will increase at constan C? (Express your answer to three significant figures.) t volume by 1,0 1.20 You currently have 1 submissions for this question. Only 3 submission are allowed.

Explanation / Answer

Amount of heat (U) = nCvT

For helium : n = 4/4 = 1 mol

Cv = 1.5R

So U = 1×1.5R×1 = 1.5R

For hydrogen considering m gram of gas will increase so

No. of moles = m/2

Cv for hydrogen = 2.5R

So 1.5R = (m/2)×2.5R×1

m = 1.2 g
