Question :
Find the internal energy of one mole of argon at 400k .
Answer :
The internal energy of one mole of argon at 400k is 4988.4 J
Given :
Temperature = 400 K
To find :
The internal energy of one mole of argon at 400K
Solution :
We know that ,
Internal energy (U) = 3/2 nRT
where R = universal gas constant
The value of R = 8.314 J mol^(-1) K(-1)
T = Temperature in Kelvin (K)
n = moles of gas
=> U = 3/2 ×1 × RT
=> U = 3/2 × 1 × 8.314 × 400
=> U = 3 × 8.314 × 200
=> U = 600 × 8.314
=> U = 4988.4
*Also we know that the internal energy of 1 mole of any two gases at the same temperature will be equal.
Hence, The internal energy of one mole of argon at 400k is 4988.4 J
