Answer to Question #73812 in Physical Chemistry for miguel de torres

Question

An experiment is performed where a 72.6 g piece of titanium metal is heated to 98.2°C. The titanium is then quickly transferred into 100.0 mL of calorimeter water at 23.5°C. The final temperature of the mixture in the calorimeter reaches 29.4°C.

a. List two assumptions that you would have to make in order to calculate the specific heat capacity of titanium.

Answer 1

Answer: The two assumptions are as follows:
1. There is no loss of heat energy when the titanium is transferred to the calorimeter, and the
titanium piece did not cool during the transfer.
2. There is no loss of heat from the calorimeter water to the surroundings (no water evaporated
from the calorimeter upon insertion of the titanium sample).
