B) Calculate the energy required to heat up 50 kg of aluminium from 200C to 3000C. The specific heat capacity is 913 J/kg K. ?
I make it approximately
We use the specific heat equation, which states that,
#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
So, we get:
Now that's a lot of heat energy!
