energy and stuff Flashcards
energy transferred when a change in temperature occurs
heat
the ability to generate heat or do work
energy
energy transferred when force is applied to produce a change in position
work
si unit is
joules (j)
energy of movement
kinetic energy
energy stored because of the physical position or chemical composition of the substance
potential energy
energy stored in chemical bonds
chemical energy
energy due to random movement of particles
thermal energy
measurement of the average kinetic energy of particles
temperature
area of the universe where the reaction or physical change takes place
system
everything in the universe outside of the system
surroundings
energy cannot be destroyed or created
law of conservation of energy
transfer of heat due to the collision of particles
conduction
transfer of energy due to the flow of fluids at different temperatures
convention
transfer of energy due to electromagnetic waves (no physical contact)
radiation
thermal energy is released by the system
exit heroic
thermal energy is absorbed by the system
endothermic
more energy was released when the bonds of the products formed than was absorbed to break bonds in the reactants
exothermic
more energy was absorbed to break the bonds of the reactants than was released when the bonds of the products formed
endothermic
can energy be converted into different forms?
yes
observable forms of energy include
heat, light, motion, sound, electricity
