science (earth,electricity and heat) Flashcards
measurement of average kinetic energy of the particles in a body
heat aand temperature
all particles of matter are in a state of constant motion
kinetic molecular theory of matter
used to measure temperatures
thermometer
fundamentl quality of matter
temperature
discovered farenheit and experimented with an ice salt solution and a thermometer
daniel farenheit
discovered celsius with pure water
anders celsius
known as lord kelvin and discovered the temperature scale kelvin
wiliam tomson
if there is no net flow of thermal energy between them”ballance of transfer of heat”
themoequilibrium
give the formula
farenheit to celsius
5/9(f-32)
give the formula
celsius to farenheit
(9/5*c)+32
give formula
celsius to kelvin
k=c+273.15
is a way of heat transfer
electromagnetic waves
occurs in solid and is direct conduction of heat
conduction
transfer of heat via electro magnetic waves
radiations
occurs in liquids and gasses,transferred by the movement of currents
convection
it is the phenomenon observed in all states of matter, process where an object expands with exposure to heat
thermal expansion
amount of heat needed to raise 1 gram to 1 degress celsius
specific heat
defines the tendency of an object to change it’s dimension
thermal expansion
change of from 1 state of maatter to another
phase changes
solid to liquid
melting
liquid to solid, molecules slow down
freezing
liquid to gas molecules speed up and if man made heat applied
vaporization
liquid to gas if natural heat is applied
liquid to gas
gas to liquid, molecules slow down
condensation
solid to gas when molecules speed up
sublimation
point at which solid changes to liquid
melting point
point at which liquid to gas
boiling point
