If 4 moles of an ideal monoatomic gas at temperature 400 K is mixed with 2 mole of another ideal monoatomic gas at temperature 700 K, the temperature of the mixture is

Options

A. `550^(@)C`
B. `500^(@)C`
C. `550K`
D. `500 K`

Answer

D

Explanation

Resultant temperature of the mixture,
`T= (m_(1)T_(1) + m_(2)T_(2))/(m_(1) + m_(2))=((4)(400)+(2)(700))/(4+2)=500K`
