4.3.1.1 Materials

Spec reference: 4.3.1 (subtopic).

What you need to know

• materials need more energy to increase their temperature than
• others.
• change in thermal energy = mass × specific heat capacity × temperature
• change
• ∆E = m × c × ∆OѲ
• Specific heat capacity is the amount of energy needed to raise the
• temperature of 1kg of a material by 1˚C.
• kinetic

Self-assessment (checklist)

• I can recall and apply the correct equation to calculate
• I can rearrange the equation linking density, mass and
• I can use the particle model to explain the different
• I can use the particle model to explain differences in
• I can recognise and draw simple diagrams to model the
• I can describe how to use appropriate apparatus
• I can calculate the volume of regular solid objects and
• I can describe how to use appropriate apparatus

Key steps (method)

• Identify what the question is testing and use the correct equation/definition.
• Show substitutions and units clearly.

Common mistakes

• Unit conversions, rearranging errors, or quoting a law without applying it.
