What are two examples of radiation mentioned in the passage?
What are two examples of radiation mentioned in the passage.
Suggested answer: Heat from the fire in Paul’s cabin and heat from the sun are two examples of radiation mentioned in the passage..
Do wooden spoons scratch Teflon?
Lean on the safe side and always use plastic (with no rough edges), wooden spoons or heat-resistant silicone utensils, spoons, and spatulas in nonstick pans. You’ll save the coating. Once a coating has a small scratch or nick, foods will stick and eventually the coating will start to peel.
How does heat travel through a metal spoon?
If a metal spoon is dipped into a cup of hot water, the end of the spoon soon feels warm. Heat is transferred along the spoon by conduction. When a point on an object is heated, the molecules there vibrate more strongly. Conduction is the transfer of these vibrations within the material.
Is it better to stir hot soup on the stove with a metal or a wooden spoon Why?
Wooden spoons give you a firm strong handle to hold, making stirring easier and more effective–and without any fear of the handle breaking. It also provides you with a solid tool for scraping things off the sides and bottom of your pan. When introduced to high temperatures, metal spoons can get really hot.
What would happen if a metal spoon were left in a cup of hot chocolate?
Conduction can also occur within a single object. In this case, energy is transferred from the warmer part of the object to the cooler part of the object by heat. Suppose you put a metal spoon into a cup of hot cocoa. … You know that when one end of a metal object gets hot, the other end quickly becomes hot as well.
Why does a wooden spoon not get hot when used in stirring hot liquid?
Metal conducts heat faster than wood — if the head of the spoon is in a hot liquid, the handle will get hot faster if it’s made out of a metal.
Can a metal spoon melt?
If you stir a warm or hot cup of liquid with a gallium spoon, the metal melts almost immediately. … It behaves much like mercury (a metal that is liquid at room temperature), but gallium is safe to handle.
What are the 4 types of radiation?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.
Why are wooden spoons bad?
Don’t use olive oil or vegetable oil because they can make wood musty. When you see wooden spoons or cutting boards be cracked, you need to remove them. It’s necessary to throw them away because food can be stuck in the cracks. … Wooden tools also can absorb smell from food with a strong smell like garlic or oil.
Which is a example of radiation from point?
Energy emitted from a source is generally referred to as radiation. Examples include heat or light from the sun, microwaves from an oven, X rays from an X-ray tube and gamma rays from radioactive elements. Ionizing radiation can remove electrons from the atoms, i.e. it can ionize atoms.
What are 4 examples of radiation?
Radiation Examplesultraviolet light from the sun.heat from a stove burner.visible light from a candle.x-rays from an x-ray machine.alpha particles emitted from the radioactive decay of uranium.sound waves from your stereo.microwaves from a microwave oven.electromagnetic radiation from your cell phone.More items…•
What conducts heat better metal or plastic?
A metal block is a better conductor and so energy is transferred more quickly to that ice cube. … Plastics are good insulators so, even though the plastic is at a lower temperature than your fingers, little energy conducts to the plastic and it feels warm.
Why does the end of a metal left in a frying pan become hot?
You might have observed that a frying pan becomes hot when kept on a flame. It is because the heat passes from the flame to the utensil. When the pan is removed from the fire, it slowly cools down. … The heat is transferred from the pan to the surroundings.
Why does a metal spoon get hotter than a wooden spoon?
Metal is a good conductor of heat while wood is a pretty good insulator of heat. … Conversely, the wooden spoon feels the same temperature as the metal spoon for an instant but it’s inherent insulating property means that it doesn’t conduct away any of your skin’s heat, thus feeling warmer.
How do you sanitize wooden spoons?
To sanitize your spoons, first clean the spoons with warm, soapy water. Next, lay the spoons on a flat surface — such as a clean baking sheet — and pour 3 percent hydrogen peroxide over them. Wait fifteen minutes, rinse the spoons off and hang them to dry.
