The specific heat of iron is 0.11 cal (g°c) . a cafeteria fork made of iron has a mass of 20 grams. how much heat energy is needed to raise the temperature of this fork from 25°c to 75°c?

The amount of energy needed is 110 calories. We know this by dong the following:
Q=20×0.11×(75−25)
⇒Q=20×0.11×50
⇒Q=110 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

You are dumb you will drop out of high school

The answer is 4 points
