Question

Find what is the ratio of the internal energy of hydrogen UB. To the internal energy of helium UJ for two moles of hydrogen and four moles of helium taken at the same temperature

Answer 1

Ration of internal energy of hydrogen to the internal energy of helium is equal to
`(5)/(6)`

Step-by-step explanation:

As we know

degree of freedom of hydrogen is 5

Degree of freedom of helium is 3

Internal energy of hydrogen

`(5)/(2) * 2 * RT = 5 *RT`

Internal energy of helium

`(3)/(2) * 4 * RT = 6 *RT`

Ration of internal energy of hydrogen to the internal energy of helium is equal to
`(5)/(6)`
