*Thermochemistry
-also related with chemical reaction
*Heat
- Increases the kinetic energy
- More collision takes palce as heat occurs
- more collision = more heat - Gay lussacs temperature and pressure
*System
- outside your house → surroundings or anything that is outside
- system inside the house or body
TYPES OF SYSTEM
*Open System
- both heat and matter can go in and out in the system
- ocean
*Closed System
- Only heat can enter the system
*Isolated System
- Matter or even heat cannot go in anf out in the system
- if heat is inside the system it cannot go out in the system
*Edothermic
- absorbed
- Heat supply / transfer
- Cooking an egg or Pancake
-More energy then release
*Exothermic
- released
- more energy is released
- "exit"
- Combustion of fuel
- Hydrogen peroxide and baking soda
- Activation Energy
- Catalyst
- frog
