I make it approximately

#### Explanation:

We use the specific heat equation, which states that,

where:

#q# is the heat energy supplied in joules

#m# is the mass of the object in kilograms

#c# is the specific heat capacity of the object, here it's in joules per kilogram kelvin

#DeltaT# is the change in temperature

Here,

So, we get:

Now that's a lot of heat energy!
