When the flame got in contact with the rod, the heat from the source transferred from the nearest tip of the metal rod to its farthest tip.

• True

• False

The heat travelled from the cooler end of the metal rod to its hotter end. 

• True

• False

When the water molecules near the bottom got exposed to heat, they became warmer and less dense which caused them to rise.

• True

• False

When the water moved farther from the heat source and reached the surface, it became cooler and denser which caused them to sink back to the bottom.

• True

• False

The heat transfers as the molecules move from a warmer place to a cooler one. 

• True

• False

Radiation allows heat to transfer through space. It is through air resistance that the sun can transfer its heat to our planet.

• True

• False

Heat is the energy of atoms and molecules in motion that move from hotter to cooler environments.

• True

• False
