Theermal Expansion
Example 3 Answer
Given an aluminum block that is 20.0 m long at 20.00 C. The coefficient for linear expansion of the material is 25.0 x 10-6/C0
What would its length be at 00 c?
Example 4 Answer
Given that the density of water at 40 C is 1.00 x 103 kg/m3. What is its density at 940 C?
Ideal Gas Law
Example 5: Answer
Assume tht air is an ideal gas. At atmospheric pressure (1 atm) and a temperature of 20 degrees C (273 degrees K) it is compressed in a cylinder to 1/9 of its original volume. Assume at the end of the compression the pressure of the compressed reaches 40 atm. What is the temperature of the air?
Example 6 Answer
A cubic box with a volume of 5.1 x 10-2 m3 is filled with air at atmospheric pressure at 20 degrees C. The box is closed and heated to 180 degrees C. What is the net force on each side of the box?
Molecular Interpretation of Temperature
