The amount of energy needed is 110 calories. We know this by dong the following:
<span>Q=20×0.11×<span>(75−25)</span></span>
<span>⇒Q=20×0.11×50</span>
<span>⇒Q=110<span> cal
Bu doing this you have the required heat represented as Q that is supposed to raise the temperature of fork that will be equivalent to the mass multiplied by the specific heat and also by the change in temperature</span></span>
