Recognise that hot objects have high temperatures and tend to cool down.
Recognise that cold objects have low temperatures and tend to warm up.
Recognise that for warm bodies the higher the temperature the quicker they cool.
State that temperature is measured in oC.
State that energy (heat) is measured in J.
Apply knowledge that the energy needed to change the temperature of a body depends on:
- mass;
- the material it is made from;
- the temperature change.
Plan an experiment to measure the energy required to change the temperature of a body.
Recognise energy flow from a hot body to a cooler one.
This will cause hotter bodies to cool and cooler bodies to warm.
Recall that temperature is a measurement of hotness.
Recall that heat is a measurement of energy.
Recognise that the specific heat capacity of materials is:
- a measure of how much energy they can hold;
- the energy needed to raise the temperature of 1kg by 1oC;
- different for different materials.
Explain that temperature can be represented by a range of colours in a thermogram.
Describe temperature as a measurement of hotness on a chosen scale.
Describe heat as a measurement of energy on an absolute scale.
State and use the equation:
energy = mass x specific heat capacity x temperature change.
(A change of subject may be required).
A thermogram of a house - why would this be useful?
