An aluminum calorimeter with a mass of 100 g contains 250 g of water. The calorimeter and water are in thermal equilibrium at 10.0°C. Two metallic blocks are placed into the water. One is a 50.0-g piece of copper at 80.0°C. The other has a mass of 70.0 g and is originally at a temperature of 100°C. The entire system stabilizes at a final temperature of 20.0°C. Determine the specific heat of the unknown sample and Using the data in Table of constants, identify of the unknown material?

I combine ice with water.  The ice has a mass of 10 kg and a temperature of -14°C.  The water has a mass of 3.5 kg and a temperature of 14°C.  What is the state of the system once it has equilbrated?     The system will be a mixture of ice and water at a temperature of 0°C.  There will be more water and less ice than the system originally contained.     The system will be all water with a temperature between 0 and 14°C.     The system will be a mixture of ice and water at a temperature of 0°C.  There will be more ice and less water than the system originally contained.     The system will be solid ice with a temperature between -14°C and 0°C.

A steel rod is 2.899 cm in diameter at 28.00°C. A brass ring has an interior diameter of 2.896 cm at 28.00°C. At what common temperature will the ring just slide onto the rod? The linear expansion coefficient of steel is 11.00 x 10-6 1/C°. The linear expansion coefficient of brass is 19.00 × 10-6 1/C°. Number Units
