I cant remember -.-
Determine the amount of energy (kJ) needed to raise the temperature of liquid water from 25C to 84C

q = mcDT .... where DT (delta-T) is Tf - Ti
You need to know the mass of the quantity of water, its specific heat capacity (4.18 J/gC) and the change in temperature. DT = 84C - 25C

E=mct
Energy= mass x specific heat capacity x change in temperature
so u need to know the mass in grams, of water, specific heat capacity is 4.2 and change in temperature is 84-25 which is equal to 59

the energy is in the form of heat here...the formula 4 calculating heat is h=mst where h is the heat, m is the mass of the substance and t is the temperature difference. given that all the units are in same scale
