What Is an Example of Conduction? — Passage
Have you ever touched a metal spoon left in a hot bowl of soup? If you have, you probably felt the heat travel up the spoon to your hand. That’s a great example of conduction—a type of heat transfer.
Conduction happens when heat moves through a solid object. In the case of the spoon, the hot soup heats the bottom of the spoon. The metal particles in the spoon start to vibrate as they get warmer. These vibrations pass from one particle to the next, carrying the heat up the spoon. Soon, the entire spoon becomes warm—even the part that’s not touching the soup!
This kind of heat transfer only works well in solids, especially in metals, because their particles are packed tightly and can easily pass energy from one to another. That’s why metals like copper, aluminum, and steel are used in cooking tools.
Another example is walking barefoot on a hot sidewalk. The heat from the sidewalk moves into your feet through conduction. If the sidewalk is very hot, it can even hurt!
To stay safe and comfortable, we often use insulators—materials that don’t conduct heat well. Oven mitts, wooden handles on pots, and rubber soles on shoes all help block conduction and protect us from burns.
The next time you feel something warm or cold after touching it, ask yourself: “Is this conduction at work?” You might be surprised by how often it happens in everyday life!
Fun Fact: That’s also why animals like penguins and polar bears have thick fur—it traps heat and slows down conduction, keeping them warm in freezing temperatures.
What is the main idea of the passage?
Why metal spoons are shinyWhat conduction is and how we experience itHow to make soup heat fasterWhat makes polar bears warmWhich is a good example of conduction?
A fan blowing airThe Sun warming your faceHeat moving through a metal spoon in hot soupA microwave heating foodWhat happens to metal particles when they get warm?
They freezeThey stop movingThey vibrate and pass heatThey melt into liquidWhy are metals good conductors?
They are shiny and lightTheir particles are spread outThey allow energy to move easily through themThey reflect heat awayWhat is an insulator?
Something that helps heat move fasterA type of metal used in cookingA material that blocks or slows down heatA tool for measuring temperatureAccording to the passage, what do oven mitts do?
Make food hotterStop soup from boilingBlock heat from reaching your handHeat your hand fasterHow does fur help animals like polar bears?
It makes them run fasterIt traps heat and slows conductionIt keeps them dry in waterIt cools them down in warm weatherWhat should you ask yourself when you feel something warm or cold?
“Is this radiation?”“Is this a new object?”“Is this soup ready?”“Is this conduction at work?”Related Content
