↪Actually welcome to the concept of the CALORIMETRY.

↪BAsically here we will use the formula of the ...

↪〽⭐Q = m s ♢t

↪since here m = mass , Q = heat , s = specific heat and ♢T = change in temperature

↪so here first we convert the power into joules as we know that . ..

↪Power = joules / sec ... since here the heater is on for 60 seconds ..

↪thus the heat energy will be = 250 × 60= 15000 joules ...

↪so after solving we get as ...
