<u>Answer:</u>

<em>49822 joules of heat can be transferred to ankle from heat bag. </em>

<u>Explanation:</u>

We know that average body temperature should be <em>37 degree centigrade </em>

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 715 \times 4.18= 2988.7 j

The degree of water that is given is 60° hence specific heat becomes179322 \ j

<em>Specific heat of body at 37° centigrade will be = 129500 \ j</em>

<em>The amount of heat that can be transferred from hot bag will be 179322 - 129500 = 49822 \ j</em>
