particel model of matter
whaat state of matter have th elowest density
gas
which state of matter has teh most kinetic energy
gas
which state of matter has highest denisty
solid
least kinetic energy in state of matter
solid
how to find density
mass divivded by volume
density unit
kg per meter cubed
change of state are physical change why
nothing change
what is the internal energy and how to fnd it
total kinetic and potential energy [ energy stored due to positiion or condition of the object]
solid to liquid ?
melting
liquid to gas
evapration
gas to liquid
condensation
solid to gas
sublimation
define specific heat capacity
teh energy required to increase the temperature of 1 kg of substnace by 1 degree celsius
specific heat capacity equation and explain them
Q= m x c x delta T
energy change[j] = mass [ any ] x heat capacity [ joules per kilogram per degree Celsius (J/kg°C)]x change in temperature[ degree celsius]
volume decrease____ increase
pressure
unit of pressure
pascal
how to find the thermal enery
mass x specific latetn heat
energy transfrred =
power x time
how to find the latetn heat
Q=ml
Q = ml is used to find______
energy realsed with latent heat of fusion or vaporization
Q = mcd elta t
to find energy neede to raise the temperature
Q= ml is only used in
phase change
q=mc(deltaT) i sonly used for
temperature change
what is q in all these equation
energy
the higher the heat capacity higher the harder it is to
heat it
what is the diffrence between latetnt heat and specific latetn heat
latent heat is energy needed for teh usbstnace to chnage state, specific latetn heat is amount of energy requied to change teh state of 1 kgof substance
