Physics Heat and Temp Review

Numbered Heads Heat and Temperature Review





1.     Definition of temperature  and association with kinetic energy increase on a molecular level.  Know mass plays no part in temperature.

2.     Understand that in thermal equilibrium there is no energy transfer and why.

3.     Know the boiling and melting points of water  and how during a phase change there is thermal equilibrium.

4.     Know the 3 widely used temperature scales and the units for energy.

5.     Know how to convert C. to F. and vice versa.  Memorize at least on form of the formula

6.     Know how to solve for  a temperature change in F  given two temperatures in C.  You cannot solve using the Temp difference in F!

7.     Solve for a delta T during an energy transfer process given Q, C  and mass.

8.     Know about temperature during a phase change and which formula is involved

9.     Interpret a heating diagram  (Q vs T) to  identify the phase changes and t calculate the latent heat of fusion or vaporization.

10.  Interpret a heating diagram  (Q vs T) to  identify the Q transferred during a single phase.

11. Convert K to C  and C to K

12.  Calorimetry  involving water where you solve for the C of an unkown metal given mass and Ti of the metal,  as well as M, C  and delta t of the water.

13. Find final equilibrium temp of a watery substance given m, Ti of the substance  when added to  a  defined mass of water where you know the initial temp of the water and the C of water.  The watery substance has the same C.
