what is specific heat capacity?
The amount of thermal energy required in a substance to raise the temperature of 1kg of the substance by 1 degrees
1 of 8
What is the formula for SHC
change in thermal energy= mass x specific heat capacity x change in temperature
2 of 8
what are the units for change in thermal energy, mass, specific heat capacity and change in temperature?
change in thermal energy=J. mass= kg. specific heat capacity=J/kg°C. change in temperature=°C

what is the practical for SHC(1-5)?
1) place a beaker on a mass balance and set it to zero. 2) fill the beaker up with water. 3)record the mass of the water. 4) place the thermometer and immersion heater. 5) record the starting temperature of the water.

what is the practical for SHC (6-8)?
6)wrap the beaker in cling film in order to stop the heat from escaping. 7) connect a joulemeter and a power pack to the immersion heater. 8)time for thirty minutes.

what is the practical for SHC(9-10)?
9) read the number of joules that passed into the immersion heater. 10) read the final temperature of the water.

what are some sources of innacuracy for SHC?
1)thermal energy passing out of the beaker into the air. 2)Not all thermal energy passing into the water. 3)incorrect reading of the thermometer. 4) thermal energy not being spread through the water.
7 of 8
what are some of the solutions for the sources of innacuracy for SHC?
1) use an insulator with a lower thermal conductivity. 2) ensure that immersion heater is fully submerged. 3) use an electronic temperature probe. 4) stir the water.
