Physics-P1-Specific Heat Capacity (PRACTICAL) 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: tonisha_Created on: 27-12-22 19:48 Specific Heat Capacity is the amount of ______ needed to raise the temperature of _____ of a substance by ____? amount of energy needed to raise the temperature of 1kg of a substance by 1 degree Celsius 1 of 21 What is the equation? change in thermal energy=m x c x temp change 2 of 21 What does m and c stand for and what are the units? m=mass=kg c=specific heat capacity=J/kg degree celcius 3 of 21 PRACTICAL --------------- Firstly what should we do with the block of desired material? measure its mass 4 of 21 Then wrap it in an? insulating layer 5 of 21 For example? newspaper 6 of 21 This reduces what? energy loss to the surroundings 7 of 21 Then insert the what two things into the holes in the block? heater and thermometer 8 of 21 Then measure the what of the block? the initial temp of the block 9 of 21 What should we connect this to? a power supply 10 of 21 What else should we connect to this? ammeter 11 of 21 Then turn the ____ ____ on and start a ______? turn the power supply on and start a stopwatch 12 of 21 The heater will do what? heat the block causing the temp to rise 13 of 21 As it heats us take readings of what two things? temp and current 14 of 21 What should we notice about the current? it stays the same 15 of 21 How often should we take these readings? every min for 10 mins 16 of 21 Then turn off the? power supply 17 of 21 Plot the results? on a graph 18 of 21 Then find the? gradient 19 of 21 In order to work out the specific heat capacity what must you do? 1/ (gradient x mass of block) 20 of 21 Then repeat using? different materials 21 of 21
