Ramu took four indentical iron balls of temperature `36^(@)C,10^(@)C,20^(@)C` and `32^(@)C` .He kept them in physical (thermal) contact with one another .After some time he measured the equilibrium temperautre attained by these four balls .What is the value of the equilibrium temperature?

Explanation

As the four bodies are indentical the equilibrium temperature is the average of the temperature
That is `t=t_(1)+t_(2)+t_(3)+t_(4)/(4)`
`=(6+10+20+32)/(4)`
