The week ahead

Hello!  For the next week we will be finishing up the physics side of chemistry.  We will have a short lesson on specific heat followed by a lab.  Please read 29 and 30 on your own, you may want to check your understanding by answering the questions at the end of 29 and 30.  There will not be a quiz over this section.

Now for some information about Specific Heat.  We know that heat gain or loss will result in a change in temperature, or a change in the state of matter.  Heat indicates a transfer of energy, if heat is lost in an object then the object itself will reflect an energy change.  Now, different objects have different heat capacities.  The specific heat capacity is the amount of heat that is required to cause 1 gram of a subjstance to change by 1°C.  Since different objects have different specific heat capacities, measuring the specific heat can help us identify an unknown substance.  For more information, refer to this link Thermal Energy.

Extended learning-  read through packets 29 and 30.  Write a one page summary about specific heat, how it works, and what it can be used for.  You may research the internet for additional information.  No copying and pasting!
