Answer:

Q = 8100 J.

Explanation:

Hello there!

In this case, according to the given information, we can infer this is a question about calorimetry, and we can use the general heat equation to solve this one:

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

Thus, we plug in the given mass, specific heat and temperatures to obtain the energy involved in this heating process:

[tex]Q=400g*0.11\frac{cal}{g\°C} (65\°C-21\°C)\\\\Q=1936cal[/tex]

Which converted to Joules turns out to be:

[tex]Q=1936cal*\frac{4.184J}{1cal} \\\\Q=8100J[/tex]
