How much energy is required to raise the temperature of 250ml of water in a 500g kettle that is 100% iron from 20°C to 99°C?
q- heat absorbed/lost
m - the mass of the sample
c- the specific heat of the substance
ΔT- the change in temperature,
The specific heat of water is 4.18J/g⋅C
Mass= 250ml = 250g
"q = 250\u00d74.18\u00d779=82.555"
