Practical: Measuring Specific Heat Capacity | GCSE Physics
Learn the systematic method for determining the SHC of a material using an immersion heater.
How do you minimize heat loss to the surroundings during the experiment?
What is Practical: Measuring Specific Heat Capacity | GCSE Physics?
"A systematic practical investigation to determine the specific heat capacity of a material (usually a metal block)."
What is the formula for density?
Why does a crisp packet puff up when taken on an airplane flight?
Calculate the pressure at a depth of 2m in water (density = 1000 kg/m³, g = 9.8 N/kg).
Specific heat capacity is the energy needed to raise 1kg of a substance by ____.
SHC Methodology
Equipment: Metal block, heater, thermometer, ammeter, voltmeter, stopwatch.
Measure mass of block and insulate it starting from room temperature.
Energy = Power x Time ($E = V I t$).
Calculate SHC using $c = E / (m Delta heta)$.
Accuracy Fact: The calculated SHC is often higher than the actual value because some energy is always lost to the surroundings (pipes, wires, and air).
