Energy used to heat water is - 52.25 kJ
Energy to heat water can be calculated by the relation given below-
Q = mc∆t
In this equation, q represents heat, m is mass of water, c represents specific heat capacity and t is change in temperature.
Values given in question are -
Mass of water is 500ml which is equal to 500g.
Specific heat capacity of water is 4.18 J/g °C.
Temperature conversion - T1 - 6°C T2 - 31° C
Keeping the values in equation
Q = mc(t2-t1)
Q = 500*4.18*(31-6)
Q = 52250 J which is equal to 52.25 kJ.
