100
a measure of the average kinetic energy of the particles in a sample of matter
What is tempature
100
the amount of energy it takes to raise the temperature of 1 kg of material 1 degree celcius
What is specific heat
100
condensation ex. hot summer day with cold glass (glass sweats)
What is gas to liquid
100
anything that takes up space and has mass
What is matter
100
gas like mixture of positive and negative particles most common state of matter in universe
What is plasma
200
the motion of particles in matter
What is kinetic theory of matter
200
the thermal energy that flows from something with a higher temperature to something with a lower tempature
What is heat
200
evaporation/ boiling gain energy water boils 100 degrees Celsius water evaporate at any temp above freezing
What is liquid to gas
200
definite shape, definite volume
What is solid
200
almost all matter expands as it gets hotter and contracts when it cools
What is thermal expansion
300
total energy of the particles in a material
What is thermal energy
300
has high specific heat 4184 J
What is water
300
melting gaining energy particles fast
What is solid to liquid
300
no definite shape, definite volume
What is liquid
300
amount of energy needed to change 1 kg of a material from liquid to gas (energy needed to boil)
What is heat of vaporization
400
temp= kinetic energy thermal= kinetic energy+potential energy
What is the difference between temperature and thermal energy
400
a hot particle bumps into those around it causing
What is a chain reaction
400
freezing loosing energy particles slow
What is liquid to solid
400
particles are held close to each other in a
What is solid
400
amount of energy needed to change 1 kg of a material from a solid to a liquid ( energy needed to melt)
What is heat of fusion
500
as the particles move faster, the average kinetic energy increased causing...
What is increase in temparture
500
low specific heat 200-300 J
What is metals
500
sublimation gaining energy ex. dry ice
What is solid to gas
500
no definite shape or volume
What is gases
500
not much of this on earth
What is plasma
