Answer:


Q=292240.8J=292.2kJ

Step-by-step explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to use the general heat equation:


Q=mC(T_2-T_1)

For us to plug the given mass, specific heat and temperature change to obtain the required heat:


Q=120g*32.91(J)/(g*K) (98\°C-24\°C)\\\\Q=292240.8J=292.2kJ
