Thermal energy/ electric Flashcards
(36 cards)
Thermal energy
The internal energy present in a system due to its temperature
Temperature
The measure of the average kinetic energy
Kinetic energy
The motion of particles in a substance. The energy resulting from movement of an object
Heat
The energy transferred from one system to another because of a difference in temperature
internal energy
Total potential energy and kinetic energy of the particles in a system
Specific latent heat
The amount of energy transfer necessary to change the state of one kilogram of a substance with no change in its temperature
Specific heat capacity
The amount of thermal energy transfer from necessary to raise the temperature of kilogram of a substance by one degree
0 degree’s into kelvin
273.15K
what are three components Kinetic molecular theory of matter
Matter is compose of tiny particles, Energy is transferred from one particle to another during collision, but at constant temperature the total energy of the system is constant, There particles are in constant, random motion and possess kinetic energy
does gas have potential energy
No
what has strong particle attraction, Gas, solid and or liquids
solids, liquids
What formula is used to find specific heat
Q= mcΔT
what formula is used to find latent heat
Q=mL
Conduction
the process by which heat or electricity is directly transferred trough the material of a substance when there is a difference in temperature
vibration of particles
convection
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise and colder denser material to sink under the influence of gravity
radiation
the emission of energy as electromagnetic which causes ionization
transfer of heat in the form of light
what is the charge of electrical energy
positive or negative
electric current
the rate of movement of electric charge carriers from one part of a conductor to another
electrical potential difference
the change in potential energy per unit charge between two defined points in a circuit
what is the symbol of electrical potential difference
Volts
power
the rate at which work is done
conversation of charge
the conservation of charge states that electrical charges cannot be created or destroyed
a cup of water has two holes. one at the top and one at the bottom. what will happen when they are uncovered. what hole will have more water coming out?
the bottom hole will have ore water coming out due to the higher pressure
1 charge is equivalent to how many what
1 electron or proton
