Interpretation:
The heat required to convert
Concept Introduction:
Specific heat of a substance refers to the quantity of heat per unit mass of substance that rises the temperature of the substance by one degree Celsius. The quantity of heat added and the specific heat is related as follows –
Molar heat of vaporization is the heat energy required to boil one mole of a substance at its boiling point.
Molar heat of fusion is the heat energy required to melt one mole of the substance at its melting point.
Answer to Problem 12.65QP
The heat required to convert
Explanation of Solution
The ice is warmed from
Mass of water is converted to number of moles. The heat required to convert one mole of ice to liquid water at its melting point is known which is termed as molar heat of fusion. The number of water in given mass of ice (water) is obtained by multiplying with the standard value.
Water is heated from its melting point
Mass of water is converted to number of moles. The heat required to convert one mole of water to steam at its boiling point is known which is termed as molar heat of vaporization. The number of water in given mass of ice (water) is obtained by multiplying with the standard value. Hence calculate the heat required to convert
We know,
The temperature of steam has to be risen from
The total heat energy utilized to convert
