Answer:


Q=330J

Step-by-step explanation:

Hello!

In this case, since the energy involved during a heating process is calculated as shown below:


Q=mC(T_2-T_1)

Whereas we consider the mass, heat capacity and temperature; we are able to plug in the given data to obtain:


Q = 20g*1.1(J)/(g\°C)(40\°C-25\°C)\\\\Q = 330J

Best regards!
