Conductors and Insulators

When something is heated, which store gets filled?

• thermal

• chemical

• electrostatic

• magnetic

Conduction is a process of heat transfer that takes place in...

• solids

• liquids

• gases

• vacuum

These transfer thermal energy quickly.

• conductors

• insulators

These are good thermal conductors.

• All solids

• Gases

• Metals

• Liquids

Metals are good thermal conductors because they have...

• free neutrons

• free protons

• free electrons

Insulators __________ the transfer of thermal energy.

• stop

• reduce

• prevent

• increase

This is NOT an insulator.

• Glass

• Paper

• Air

• Aluminium

Transfer of thermal energy ALWAYS happens in this direction.

• HOT to COLD

• COLD to HOT

This instrument is used to measure volume of a liquid.

• thermometer

• digital balance

• measuring cylinder

• funnel

This is the variable you change in an experiment.

• independent variable

• dependent variable

• control variable
