What is the total internal energy of 1.00 mole of an ideal gas at 100$^{\circ}$C?

Question

Quizplus · Accepted Answer

To calculate the total internal energy of a gas, we can use the equation:

U = (3/2) nRT

where U is the internal energy, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

First, we need to convert the temperature given in Celsius to Kelvin:

T = 100°C + 273.15 = 373.15 K

Substituting in the values:

U = (3/2) (1 mol) (8.31 J/mol*K) (373.15 K)

U = 4,650 J

Therefore, the answer is B.

What Is the Total Internal Energy of 1 ∘^{\circ}∘ C? A) 5,230 J B) 4,650 J C) 4,040 J
