Question

The temperature of piece of copper of mass 250g is raised to 100% and is then transferred to well lagged aluminum can mass 10g containing 120g of methylated spirit at 10%.

Calculate the final steady temperature after the spirit has been well stirred. Neglect the heat capacity of the

C for copper= 400j/kg/k

C2 methylated spirit = 2400j/kg/k

C for alluminium = 900j/kg

What are we neglecting?
It is a problem to me
