# Specific heat and calorimetry

This is a problem we did in lab that dealt with measuring specific heat.

Please provide answers along with solutions to the following questions.

These problems mainly deal with specific heat capacity.

See attached file for full problem description.

A. What is the energy gained by water? Include measurement uncertainty?

B. What is the energy gained by the cup? Include measurement uncertainty?

C. What is the Energy lost by the block? Include measurement uncertainty?

D. What is the specific heat of the block? Include measurement uncertainty?

#### Solution Summary

The solution gives the calculations of an experiment to determine the specific heat of the material of a block by calculating the amount of heat given and taken by the substances when they are mixed and then to find the specific heat.

Specific Heats and Atomic Masses Using a Calorimeter

ChemLab program "specific heat" lab.

Obtain 100 g shots of each: iron; copper & aluminum. Insert 150 ml of water at room temperature and heat to a

final temperature of 100 degrees of celsius.

Place in calorimeter and add 100 ml of water 20 degrees celsius.

Measure specific heat for each metal and atomic weight.

100 gm of each Fe; Cu; Al; initial temperature of each 20 degrees C; Final temp. of each 100 degrees C initial temp. of 100 ml of water; 20 degrees ; final temp of water in calorimeter: for Fe 28 degrees C; for Cu 27 degrees C; for Al 30 degrees C. determine specific heat for each metal and estimate atomic weight for each metal. Use 1 cal/gram *C for water.
