C in thermochemistry
WebHow much heat, in kilojoules, will be required to heat a 500.0 g sample of lead from 23.0 °C to its melting point and then melt it? Solution: 1) Two calculations are required: 1) heat … Weband C is called heat capacity. Heat capacity tells how much energy required by a substance to raise its temperature by 1°C. It has a unit of J/°C. We can make heat capacity dependent on mass, it means that, q = m csp ΔT …
