Question

An insulated container is used to hold 40.30g of water at 15.0 Celsius. A sample of copper weighing 16.20g is placed in a dry test tube and heated for 30 minutes in a boiling water bath at 100.10 Celsuis. The heated test tube is carefully removed from the water bath with laboratory tongs and inclined so that the copper slides into the water in the insulated container. Given that the specific heat of solid copper is 0.385 J/(g * Celsius), calculate the maximum temperature of the water in the insulated container after the copper metal is added.

I have no idea how to do this. Please show me how to do it.

Explanation / Answer

Heat lost by copper = Heat gained by water

16.2*.385*(100.16-T) = 4.18*40.30*(T - 15)

on solving above equation we get,

T, final temperature = 18.04 degree celcius
