Specific Heat Capacity Required Practical - GCSE Physics Summary
Channel: Kit Betts-Masters
Date: 14/01/2021

Required Practical 1: Specific Heat Capacity
Measure the mass of your block using a balance.
Measure starting temperature with a thermometer and turn on powerpack.
Heat for 5 minutes.
Measure final temperature with a thermometer.
Calculate temperature rise by subtracting start temperature from final temperature.
Calculate energy transferred using 𝐸=𝑃𝑡. (Power of the heater is 50W)
Calculate specific Heat Capacity using 𝑐=∆𝐸/𝑚𝑐
Other channels cover the content but GorillaPhysics will help you get the grade 9 or that A* at A Level.

Evaluation Points
Accuracy:  Use of a thermometer, keep bulb submerged, read from right angle to scale.  Use a longer time for more accurate timing.  
Precision:  Repeated measurements give little scatter.  
Systematic Error:  Energy also transferred by heating to surroundings, values of specific heat capacity usually slightly too high, insulate block.
