the particle model of matter-phy3

Question 1

what is the definition of specific latent heat of fusion?

Answer 1

it is the amount of energy required to change the state of 1kg of substance from solid to liquid without changing its state

Question 2

structure of solids:

Answer 2

particles are linked by strong forces
packed close together and move very little
specific and regular pattern

Question 3

the temperature in which a solid turns into a liquid

Answer 3

melting point

Question 4

the temperature in which a liquid turns into a gas

Answer 4

boiling point

Question 5

density

Answer 5

mass/volume

Question 6

the density of solids

Answer 6

solids have the highest density as the particles are close together

Question 7

the density of gases

Answer 7

gases have the lowest density as the particles are far apart

Question 8

condensation:

Answer 8

gas to liquid

Question 9

particles of gases-temperature

Answer 9

the higher the temperature the higher the average kinetic energy of the particles
