Conduction

Heat energy always transfers FROM ​ (a)   TO​ (b)  

• hot
• cold
• high
• low
• solid
• gas

Put the statements in order to explain how conduction occurs

• The Bunsen burner transfers heat energy to the particles of the solid

• The particles further along begin to vibrate more as they increase in heat energy

• The particles immediately over the Bunsen burner vibrate more

• Particles collide with particles next to them, transferring energy and cause the neighbouring particles to vibrate more

• The solid is now all the same temperature

A poor conductor of heat is called an __________

Why are gases poor conductors of electricity?

• Particles are close together and collisions are more frequent

• Particles are far apart and collisions are less frequent

• Particles are close together and collisions are less frequent

• Particles are far apart and collisions are more frequent

Why does a cold ice lolly melt on a warm tongue?

• Thermal energy transfers from the ice lolly to the tongue .

• Thermal energy transfers from the tongue to the ice lolly.

• Thermal energy does not transfer.

• Thermal energy from the sun melts the ice lolly.
