The statement “The temperature at which a solid changes into a liquid is called the boiling point” is not correct. The temperature at which a solid changes into a liquid is called the melting point (or fusion point). The boiling point is the temperature at which a liquid changes into a gas.<\/section>\n
This question tests knowledge of basic heat transfer mechanisms and phase change terminology.<\/section>\n
Conduction is the transfer of heat through direct contact, most effective in solids. Convection is the transfer of heat through the movement of fluids (liquids or gases). Radiation is the transfer of heat through electromagnetic waves, which can occur even in a vacuum.<\/section>\n","protected":false},"excerpt":{"rendered":"
