Question

A piece of aluminium of mass 260g is cooled in a freezer. It is then dropped into 140 g of water at 5°C, causing 4.0g of water to freeze. Determine the temperature inside the freezer.​

Answer 1

Answer:

The equation for heat is

Q=m(tf−ti)Cp

Q = heat in Joules

m = mass in grams

tf = final temp

ti = initial temp

Cp = Specific Heat Capacity

For this problem

Q=???

m=275g

tf=38.4oC

ti=85.2oC

Cp=4.18jgoC

Q=275g(38.4oC−85.2oC)4.18JgoC

Q=275g(−46.8oC))4.18JgoC

Q=−53,796.6J

The negative Joule value means heat is being lost in an exothermic reaction.
