mrs. wilson poured hot tea into a cup and stirred it with a metal spoon. after a few moments, she noticed that the spoon was getting warm. what is the best explanation for why this occurred? (1 point)\nthe spoon is a conductor\nthe spoon reflects heat\nthe spoon is an insulator\nthe spoon was warmed by radiation
Answer
Explanation:
Step1: Understand heat transfer
Heat can transfer through conduction, convection, and radiation. Conduction is the transfer of heat through a material without the movement of the material itself.
Step2: Analyze the situation
A metal spoon in hot tea gets warm because heat is transferred from the hot tea to the spoon through the metal. Metals are good conductors of heat.
Step3: Evaluate options
- The spoon is a conductor: This is correct as metals conduct heat well and heat is transferred from the tea to the spoon.
- The spoon reflects heat: This is not relevant as reflection is not the reason for the spoon getting warm here.
- The spoon is an insulator: Metals are not insulators, so this is incorrect.
- The spoon was warmed by radiation: Radiation is heat transfer through electromagnetic waves and is not the main process here as the spoon is in direct contact with the tea.
Answer:
The spoon is a conductor
