1
Q
conduction
A
the transferrence of thermal energy through neighbouring particles, occuring through all states of matter.
2
Q
conduction - when atoms are hot their…
A
vibrations increase. when one atom collides with another, this energy transfers and the heat is conducted from one substance to another.
3
Q
what is a conductor?
A
a material in which heat can easily pass through
4
Q
what is an insulator?
A
a material in which heat cannot easily pass through
5
Q
what is the process of convection
A
particles gain thermal energy from the heat and spread out, this warm air rises, it then cools as it moves away from the heat. the cold air particles come closer together, and sink because they are heavy.
