Energy and its Forms G.4 Flashcards
it’s the law about lowering vapour pressure
(G.3)
Raoult’s law
define as “Energy in Motion”
Kinetic energy
considered as the “Energy at rest”
Potential Energy
Law of conservation of energy
energy is neither created nor destroyed but is converted from one form to another
Forms of energy
- Mechanical Energy
- Radiant or light energy
- Electrical Energy
- Thermal or Heat Energy
- Chemical Energy
- Nuclear Energy
results physical work
Mechanical Energy
results from electromagnetic waves
Radiant or light energy
comes from moving charges
Electrical Energy
comes from the constant motion of molecules
Thermal or Heat Energy
stored within the structure units of substances
Chemical Energy
comes from nuclear reactions
Nuclear Energy
defined as the transfer of thermal energy
Heat
particular area of interest
System
everything outside the area of interest
Surrounding
Classifications of system
open, closed, or isolated
allow the transfer of mass and energy
Open system
do not allow the transfer of mass and energy
Isolated systems
allow the flow of energy but not mass
Closed systems
process of transferring heat from the system to the surroundings
Exothermic process
process of heat exist the system. If the flow of heat is form the surroundings to the system
Endothermic process
