An insulated lunch bag keeps food warm by
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.
When a fork is placed in a hot piece of lasagna, thermal energy is transferred up the fork by
While Felicia is stirring her hot coffee with a metal spoon, she gets called away. She sets the coffee on the desk and then forgets to come back for it before going home for the weekend. How long will conduction between the spoon and the hot coffee occur?
Kai takes a hamburger off of the grill and puts a piece of cheese on it. Explain how and why the cheese melts when Kai puts it on the hamburger.
The cheese melts because of conduction, which occurs when two objects of different temperatures are in direct contact. Since the hamburger is warmer than the cheese, thermal energy is transferred from the hamburger to the piece of cheese, causing the temperature of the cheese to rise and eventually melt.
