Question

How many joules of heat would be required to heat 0.5 kg of aluminum by 2K?

Answer 1

`902` `J`

Explanation:

Use the equation `Q=mcdeltaT`

Where `Q=`heat flow, `m=`mass, `c=`specifc heat capacity of `Al` and `deltaT=`change in temperature

Just looking up the specific heat capcity of aluminum off google, which is `0.902` `J/(g*C)`

Sub values in with their correct units (the change in the kelvin scale is the same in celsius)

`Q=(500g)*0.902(J/(g*C))*(2` celsius)

`Q=902` `J`
