Answer:
Heat energy required = 252000J or 252KJ.
Explanation:
Given the following data;
Mass = 3kg
Temperature = 20ºC
Specific heat capacity of water = 4200 J/kg°C
To find the heat energy required;
Heat capacity is given by the formula;
[tex] Q = mct [/tex]
Where;
- Q represents the heat capacity or quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity of water.
- t represents the temperature.
Substituting into the equation, we have;
[tex] Q = 3*4200*20 [/tex]
Q = 252000 Joules or 252 Kilojoules.
