Heat Energy

Question 1

Define Conduction

Answer 1

Conduction is the process of heat energy transmitting through collision between particles

Question 2

Define Convection

Answer 2

Convection is a process which heat travels through the movement of liquids or gases transporting their energy from hotter areas to cooler areas

Question 3

Define radiation

Answer 3

Radiation is a process of heat transfer without the presence of particles as electromagnetic waves.

waves are emitted and are absorbed by an object

Question 4

How does thermal conductivity differ between metals and non-metals? Explain.

Answer 4

Metals have free electrons which are not bounded to atoms, allowing electrons to freely move around in metal.

Question 5

Explain why metals are generally good conductors of heat compared to non-metals.

Answer 5

Metals usually have better thermal conductivity than non metals due to the way their atoms are structured.

The structure of atoms in metals allow heat to flow through easier.
