Answer:
49822 joules of heat can be transferred to ankle from heat bag.
Explanation:
We know that average body temperature should be 37 degree centigrade
Hot water bag has 715 grams of water present in it. Specific heat of 1 gram of water is 4.18 joules per gram per degree centigrade. 715 grams will have [tex]715 \times 4.18= 2988.7 j[/tex]
The degree of water that is given is 60° hence specific heat becomes[tex]179322 \ j[/tex]
Specific heat of body at 37° centigrade will be = [tex]129500 \ j[/tex]
The amount of heat that can be transferred from hot bag will be [tex]179322 - 129500 = 49822 \ j[/tex]
