Answer:

[tex]Q=330J[/tex]

Explanation:

Hello!

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

[tex]Q=mC(T_2-T_1)[/tex]

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

[tex]Q = 20g*1.1\frac{J}{g\°C}(40\°C-25\°C)\\\\Q = 330J[/tex]
