Question

When hot water is mixed with cold water, the mixture attains an intermediate temperature because :

• A. heat flows from body at higher temperature to body at lower temperature
• B. the two fluids mix uniformly speeding up the heat transfer process if cold water is poured over hot water
• C. both A and B
• D. neither A nor B

Answer 1

The correct option is C both A and B

When hot water is mixed with cold water, the mixture attains an intermediate temperature because heat flows from higher temperature to lower temperature. When cold water is poured over hot water, cold water being denser flows to the bottom mixing with the hot water in the process and getting heated up.
