Two different substances, Substance A and Substance B, are in direct contact with each other and are at different temperatures. The particles in Substance B are vibratingthe particles in Substance A. This means Substance B isSubstance A and conduction will.
A recipe for candy requires that the liquid ingredients be stirred constantly until the liquid reaches a temperature of 140°C. What type of spoon – wood or metal – will prevent burns to a person’s hand while stirring the hot liquid? Explain your choice.
A wooden spoon should be used because wood is an insulator. Insulators slow the transfer of thermal energy, preventing the heat from the 140°C liquid from reaching the person's hand. In contrast, a metal spoon is a conductor and would quickly transfer heat, potentially causing a burn.
