Physics GCSE question URGENT ANSWER NEEDED

A student investigated how the mass of water in an electric kettle affected the time taken for the water to reach boiling point. the kettle switched off when the water reached boiling point. figure 4 shows the kettle. the power of the kettle was 2.6kW the kettle took 120 seconds to heat 0.80 kg of water from 18°c to 100°c Calculate the specific heat capacity of water using this information give your answer to two decimal place

energy transferred (joules)= power(watts) x time(seconds)
1kW=1,000 watts
energy change(joules)=mass (kg)x specific heat capacity(J/kg°C) x change in temperature(degrees celsius)
