Calculating Specific Heat Worksheet

Name: ___________________________________ Date: _________

Q = mcT , whereQ = heat energy,m = mass, and T = change in temp.

Remember,T = (T final Tinitial).Show all work and proper units.

1. A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and itstemperature changes from 5!" to 175!". "alculate the speci#c heat capacity ofiron.
