Thermal Expansion Flashcards
1
Q
how much do solids expand
A
only a small amount
2
Q
liquids expansion
A
they expand a bit more than solids
3
Q
gas expansion
A
they expand the most
4
Q
why do they expand
A
due to increase in energy of the particles.
5
Q
what is a specific heat capacity
A
the amount is the amount of energy needed to heat 1kg of material by 1 degree
6
Q
what does energy equal
A
mass x specific heat capacity x change in temp
7
Q
difference between evaporation and boiling
A
boiling is the change of state and evaporation can happen at any temp.
8
Q
latent heat
A
melting point is known as latent heat of fusion.
boiling point is latent heat of vaporisation.
9
Q
conduction
A
heat transfer mainly in solid. Metals are best due to free electrons. Heat transfer by collision of particles.
