==Key Stage 4==
===Meaning===
Determining the [[Specific Heat Capacity|specific heat capacity]] of a [[metal]] block.
===Experiment Version 1a===
====Variables====
: [[Independent Variable]]: The [[temperature]] of the [[metal]] block.
: [[Dependent Variable]]: The [[energy]] supplied to the [[metal]] block by [[heating]].
: [[Control Variable]]s: The [[mass]] of the [[metal]] block.
====Method====

#Attach a [[Joulemeter]] and [[Power Supply|power supply]] to an [[Immersion Heater|immersion heater]].
#Place the [[Immersion Heater|immersion heater]] and the [[thermometer]] in holes in the [[metal]] block.
#Place a drop of [[water]] in the [[thermometer]] hole to ensure [[Thermal Contact|thermal contact]] between the [[thermometer]] and the [[metal]] block.
#[[Reading|Read]] and record the initial [[temperature]] of the [[metal]] block.
#Switch on the [[Power Supply|power supply]].
#Record the [[reading]] on the [[Joulemeter]] with every 2°C increase in [[temperature]].
====Improving [[Accuracy]]====
: Place the [[metal]] block on a [[Heatproof Mat|heatproof mat]] to reduce the [[Thermal Energy Store|thermal energy]] lost to the table surface by [[Thermal Conduction|conduction]].
: Wrap the [[metal]] block a [[Thermal Insulator|thermal insulator]] to reduce the [[Thermal Energy Store|thermal energy]] lost to the [[air]].
: Complete the [[experiment]] in [[temperature]] range close to [[Room Temperature|room temperature]] to reduce the rate of [[Energy Transfer|energy transfer]] from the [[metal]] block to the surroundings.
====Improving [[Precision]]====
: Use a [[thermometer]] with a higher [[resolution]].
: Use a [[Data Logger|data logger]] rather than a [[thermometer]].
