Question

how many joules of heay are needed to raise the temperature of 10.0 g of aluminum from 22°c to 55°c, if the specific heat of aluminium is 0.90J/g°c

Answer 1

The heat energy required to raise the temperature is 297 joules.

The energy required is calculated by the formula

Q=mCΔT

here, m is the mass, C is the specific heat, ΔT is the temperature difference

Plugging the given values in the above equation

Q=10­­×0.90×(55-22)

=297 joules

The heat energy required to raise the temperature is 297 joules.
