I Do - A 2kg sample of salt water was heated up by 10⁰C. The specific heat capacity of salt water is 3985 J/kg ⁰C. Calculate the energy change in Joules to 2dp.
We Do
A 1kg sample of paraffin was heated up by 13⁰C. The overall energy change was 30,000J. Calculate the specific heat capacity to 2dp.
You Do
A 5.4kg sample of oil was heated up by 8⁰C. The overall energy change was 40000J. Calculate the specific heat capacity to 2dp.
You Do
When the car engine is working normally, 2 kg of coolant passes through the radiator each second. The temperature of the coolant falls from 112 °C to 97 °C. Specific heat capacity of the coolant = 3800 J/kg °C.
Calculate the energy transferred each second from the coolant.
Calculate the specific heat capacity of a block of unknown metal using this data.
Mass = 2kg, temperature change = 7⁰C and energy = 1240J
