Answer:
The internal energy is 73.20 J.
Explanation:
Given that,
Weight of helium = 86 mg
Temperature = 0°C
We need to calculate the internal energy
Using formula of internal energy
Where, = specific heat at constant volume
He is mono atomic.
So, The value of
now, 1 mole of Helium = 4 g helium
n =number of mole of the 86 mg of helium
T = 0°C=273 K
Put the value into the formula
Hence, The internal energy is 73.20 J.
34.916 is the answer to 67.786-32.87 . I found this answer by using a calculator.
