A vessel contains `110 g` of water. The heat capacity of the vessel is equal to `10 g` of water. The initial temperature of water in vessel is `10^(@)C`. If `220 g` of ho, water at `70^(@)C` is poured in the vessel, the final temperature neglecting radiation loss, will be

A

`70^@C`

B

`80^@C`

C

`60^@C`

D

`50^@C`

Text Solution

Verified by Experts

The correct Answer is:
D
`220S(70-theta)=(110+10)s(theta-10)`
`11(70-theta)=6(theta-10)`
`770-110=60-60`
`170=830`
`thetacong50^@C`
