How is this for number 4. heaters temperature. Each material has a speficif heat capacity which means that they all heat up at different times because of how they absorb the energy. In this lab the iron heat up quicker due to the fact that it has a low specific heat capacity. I observed that the quick increase in temperature. For the brick, it heated up slower because it has less specific heat capacity than the iron. The water had a slow increase in temperature, this is because it has a high specific heat capacity which allows the water to absorb a lot of energy with small change in temperature. The olive oil has a lower specific heat capacity which means that the temperature increases faster than water. The olive oil heated up slower than the iron and brick though. The thermal energy change in each was related to its mass and the specific heat capacity
