Define Heat (2)
- Heat - the energy that causes there to be changes in matter (measured in calories)
- 1. amount of heat necessary to raise the temperature of one gram of water 1degree C
- 2. calories= # of grams of water X # degrees change in temperature
-
What is used to measure heat?
Temperature
-
What is used to measure temperature?
Celsius and Kelvin
-
Temperature is
the hotness or coldness o
-
Degree Celsius or Degree Centigrade
Used in most scientific study
-
Kelvin Scale
- Used in many mathematical formulas of chemistry
- -0 K is absolute zero
- -an abstract number
- -when all things in the universe come to a halt
-
Conversion from Celsius to Kelvin(Absolute)
K= C +273
-
Conversion Kelvin (Absolute) to Celsius
C= K - 273
-
Chart of Required Temperatures
- C K \
- Normal Body Temp. 37 310
- Freezing point of water 0 273
-
Define Energy
The ability or capacity to do work
-
Define Potential Energy
Stored Energy- Has the potential to do work
-
Examples of Potential Energy

-
Define Chemical Energy
Energy associated with chemical reactions
-
Define Exothermic Reaction
Absorbs heat (feels cool)
-
Define Exothermic Heat
Releases heat (feels hot)
-
The Law of Conservation of Energy
- -Energy is neither created not destroyed in a chemical reaction
- -only changed in form
-
The Law if Conservation of Matter (Mass)
-Matter (Mass) is neither created nor destroyed in a chemical reaction
-
The Law of Conservation of Matter and Energy
- - In any type if reaction, mass or energy can be neither created or destroyed; they can only be interconverted(change one to other).
- -nothing is lost in the reaction
-
A measure of the gravitational attraction of the earth for a body is
Weight
-
