A15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°c to 175°c. what is the specific heat capacity of iron?

Explanation:

The heat absorbed by the piece of iron is given by:

where here we have

Q = 1086.75 J is the heat absorbed

m = 15.75 g is the mass of the piece of iron

Cs is the iron's specific heat

is the change in temperature of the piece of iron

If we re-arrange the formula and we solve for Cs, we find the iron's specific heat capacity:

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
