A cook pours L of ice water at
Amount of hot water in the pan.
Answer to Problem 66A
Amount of hot water in the pan is,
Explanation of Solution
Given :
Volume of ice water at
Temperature of hot water,
Temperature of mixture,
Formula used :
Where, Q is amount of heat generated, m is mass, c is specific heat and
Calculation :
Density of water is,
Volume of cold water,
Therefore, mass of cold water,
Let mass of hot water is
According to heat transfer heat lost by hot water is equal to heat gained by cold water.
Density of water is,
Therefore, volume of hot water,
Conclusion :
Therefore, 3 L hot water was in the pan.
