Water has the highest specific heat capacity and metal has the lowest. 6. Here are the heat capacities of the four substances: 0.10 cal/g °c, 0.25 cal/g °c, 1.0 cal/g °c, & 0.2 cal/g °c. Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about specific heat capacity (GCSE and Key Stage 3) Heat capacity is how much heat an object can absorb before it increases in temperature. I really enjoy teaching students about specific heat capacity but try to relate this abstract idea to some concrete examples.

There are published tables of molar specific heats of many materials. Note that the specific heat equation does not apply for phase changes. This is because the temperature does not change. When working a problem, you'll either be given the specific heat values and asked to find one of the other values, or else asked to find specific heat.
