Question

In an insulated vessel, a quantity of hot water at temperature T1 is mixed with a different quantity of cold water at temperature T2. After equilibrium is established, the vessel contains __________.

A. steam only
B. ice only
C. water and ice
D. water only

Answer 1

Answer:Water Only

Step-by-step explanation:

Given

vessel is insulated therefore no heat can be added or removed i.e. heat exchange is zero

If hot water at
`T_1` is mixed with cold water at
`T_2` then at equilibrium vessel contains only water and final temperature of water will be between
`T_1` and
`T_2`

Heat released by hot water is equal to heat gain by cold water .
