Why is the metal spoon in your cup of hot chocolate hot?
Metal is a good conductor of heat
. The heat energy moves from the hot liquid through the spoon by conduction. Houses are usually insulated with materials that do not transfer thermal energy well.
Why doesn't a plastic spoon in your cup of hot chocolate feel hot?
The heat energy moves from the hot liquid through the spoon by conduction. Why doesn't a plastic spoon in hot chocolate feel hot?
Plastic is a poor conductor of heat energy
. … The insulating materials hold the heat in the house.
What happens when you place a metal spoon in hot chocolate?
When they are heated, they move faster and when they are cooled, they move slower. For example, if you put a room-temperature metal spoon into a hot liquid like soup or hot chocolate,
the metal gets hotter
.
What type of heat transfer is the spoon getting hot when stirred in hot chocolate?
Spoon because the spoon is cooler than the hot chocolate Heat moves from warmer to Cooler objects.
Conduction transfers
heat from the hot chocolate to the spoon.
Why is it that if you leave a metal spoon in a bowl of hot chili is becomes warm?
Explanation:
Some of the heat energy from the water is transferred to the metal by the direct contact of the water molecules with the metal molecules of the spoon
.
What would happen if a metal spoon were left in a cup of hot chocolate?
Heat is transferred from your hands to the hot cocoa in the cup. Energy is created. Q. If you leave a metal spoon in a pot on the hot stove
the spoon gets hot too
.
What are two ways that Earth's atmosphere gets heated?
Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including
radiation, conduction, and convection
. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection.
What happens when you put a metal spoon in hot water?
Metals are generally good conductors of heat. …
The rapidly moving molecules in the boiling water bump the molecules in the metal spoon
. This bumping transfers kinetic energy to the molecules that make up the spoon, causing them to vibrate faster.
What happens when a spoon absorbs heat?
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.
What happens when you put hot metal in cold water?
If you add cold water to a hot pan, the temperature in the metal drops locally (where the water touches the metal) and
since metal extend with heat, cooling them down contracts them
. … This property of metal can be characterized by the thermal expansion coefficients.
What kind of heat transfer caused the chocolate to melt?
| A B | Conduction Chocolate melting in your hand. | Conduction Ironing a shirt. | Conduction Touching a hot stove. | Conduction Holding a hot cup of coffee. |
|---|
What type of heat transfer occurs when holding a cup of hot chocolate?
if you hold a paper cup containing hot chocolate in your hand,
thermal energy
. the transfer of the thermal energy in a fluid by the movement of warmer to colder; heating a fluid and it raising. You just studied 18 terms!
When a spoon is left in a bowl of hot soup?
Conduction is the transfer of energy through matter from particle to particle. It is the transfer and distribution of heat energy from atom to atom within a substance. For example, a spoon in a cup of hot soup
becomes warmer
because the heat from the soup is conducted along the spoon.
Which part of the spoon heated first?
2. Why is the part of
the spoon over the flame
get heated first than the other parts? The part of the spoon over the flame get heated first than the other parts because it is closer to the heat source.
Which of the following best explains why the end of a spoon sticking out of a cup of hot water also gets hot just like the end of the spoon in the hot water?
Which of the following best explains why the end of a spoon sticking out of a cup of hot water also gets hot?
The hot water causes a chemical reaction to take place in the spoon. The hot water heats the air surrounding the upper part of the spoon.
What are 4 examples of radiation?
- ultraviolet 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.
