Question

which would require more heat to raise its temperature by 10 degree celcius -1 kg of almunium or 1 kg of copper?​

Answer 1

Answer:

It will be the copper.

Reason: copper has a lower specific heat than does aluminum.

Specific heat:

If heat Q is supplied to a mass m of a material, the resulting change DeltaT in the materials temperature can be calculated from the equation

Q = c m DeltaT

where c is the “specific heat” of the material.

If the copper and aluminum have the same mass m and the same heat Q is supplied, then they will have the same value of c DeltaT.

Hence DeltaT of the mass with lower specific heat c will have the higher DeltaT.
