Unit 10.4.2 - Absorbing and measuring heat energy
Following on from the discussions of the previous class, it should be noted that the temperature change in a body is directly proportional to the energy applied and inversely proportional to the mass being heated.
E = kΔT
E = k'/m
The class is provided with a worksheet on calorimetry.
Student follow up
Practice calculations on calorimetry
The students could be directed towards means of reducing heat losses in their community. It could be explained that a huge amount of waste takes place in most environments leading to increased costs and inefficiency.
They could identify areas in which heat losses occur in the local or global environment
