True. Heat travels through solids by conduction, which is the transfer of heat through direct contact between particles within the material. This process occurs as the faster-moving particles transfer energy to neighboring slower-moving particles.
False. Heat travels by conduction when molecules transfer kinetic energy to adjacent molecules through direct contact. When molecules stop moving altogether, conduction cannot occur as there is no kinetic energy to transfer.
True. Sound can travel through solids, liquids, and gases. The speed and manner in which sound travels may vary depending on the medium through which it is moving.
Conduction requires a medium to transfer heat (false - conduction can occur in solids, liquids, and gases). Only metals can conduct heat (false - materials like ceramics and glass can also conduct heat). Conduction only occurs at a constant rate (false - the rate of conduction can vary depending on factors like temperature and material properties).
False. The transfer of energy in the form of invisible waves is called radiation, not conduction. Conduction is the transfer of heat through direct contact between substances.
False. Sound travels faster and more efficiently through liquids than through gases because liquids are denser and allow sound waves to propagate more quickly.

True
False - that's a volcanic eruption.
Solids do conduct heat better than gases, although not necessarily better than liquids. Some solids are actually composite materials, because they can have a porous structure which contains gas within the solid, and this results in solids that do not conduct heat very well. But it is the gas component which has this insulating property.
False... The flow of heat through direct contact is conduction.
False. Sound travels faster and more efficiently through liquids than through gases because liquids are denser and allow sound waves to propagate more quickly.
False. When you walk barefoot on hot sand, heat is transferred to your feet through conduction, not radiation. Conduction is the transfer of heat through direct contact between two materials at different temperatures.
