The specific heat of iron is 0.11 cal/goc. a cafeteria fork made of iron has a mass of 20 grams. how much heat energy is needed to raise the temperature of this form from 25oc to 75oc? 0.044 calories 0.275 calories 110 calories 9090.9 calories

110 cal

It is given that he specific heat of Iron is .

Mass of iron fork 20 g

Heat energy is needed to raise the temperature of this from

we can use the following formula to calculate heat energy:

where Q is the heat required to raise the temperature by of a mass m having specific heat C.

Insert the values:

Thus, heat required to raise the temperature of iron fork is 110 cal.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid
