Answer:
Though the changes in the specific heat of milk between 15.0° C. and 60.0° C. are not great; still there is shown by our data a fairly pronounced maximum at about 30.0° C.
This is due to specific heat value of milk (Cp=3.93 kJ/kgK) being lower than that of water(Cp=4.18 kJ/kgK). (Specific heat is defined as the amount of heat required to raise temperature of unit mass of substance by a unit degree.)
Explanation:
It depends upon the value of specific heat.
Specific heat means how much amount of heat energy required to increase the temperature by one degree celcius for 1kg of mass.
For ur question, Take one kg of water and one kg of milk in separate jar and place it in gas stove and give same level of gas supply to both jar. Measure the temperature rise in both the jar, obviously temperature of milk will rise quickly than water. this is because of specific heat value
The degree of hotness is measured by temperature. If we have same quantity of water and milk at same initial temperature, and suppose we need to increase temperature of both to a predefined temperature then milk will get heated to that temperature faster.
This is due to specific heat value of milk (Cp=3.93 kJ/kgK) being lower than that of water(Cp=4.18 kJ/kgK). (Specific heat is defined as the amount of heat required to raise temperature of unit mass of substance by a unit degree.)
Milk boils at higher temperature because of completely different phenomenon called "Boiling point elevation" which results primarily due to difference in their specific gravity
