Why would a wood floor feel colder than a floor covered with carpet?
what is Wood floor conducts heat better than carpet
What type of heat transfer is involved when you heat a room?
what is convection
Water is heated in a pot on a stove. The cooler, denser water at the surface sinks and pushed the warmer water to the top. What heat transfer is this an example of?
what is convection
What type of heat exchange involves the collision of particles?
What type of heat transfer involves holding a hot bowl of soup?
what is conduction
What type of energy is involved when you heat water in a pot on a stove?
what is thermal
What type of heat transfer is involved when the Sun heats a sidewalk?
what is radiation
Explain the path of conduction when you place steak in a pan on a hot stove.
what is stove to pan to steak
What type of heat transfer is involved in heating soup in a pot on a stove?
what is convection
What is the best conductor of heat and electricity?
what is metal
What type of heat transfer is involved when a pan is being heated on a stove?
what is conduction
What is heat?
what is The transfer of thermal energy from one object to another
What type of energy is transferred to a pot to make the water inside it boil?
what is heat/ thermal
How is energy transferred when an ice pack is applied to a sprained ankle?
what is Heat energy is transferred by conduction from the ankle to the ice pack
Why is copper used in house wiring?
what is Cause it’s an electrical conductor
How does a blanket keep you warm on a cold night?
what is The blanket decreases the transfer of thermal energy from your body to the air
You pour ice water into four cups. Each cup is made of a different material; foam, glass, metal, plastic. Which material will be coldest to the touch after one minute? Why?
what is Metal because it is a better conductor of heat and will transfer the heat away from it quickly
What happens to thermal energy when you hold a cup of hot cocoa in your hands?
what is As you hold the cup of hot cocoa, the heat moves to your hands
A heater is turned on to heat a room by convection. Where in the room would the hottest air be located?
what is Near the ceiling
During a lab, a metal rod is connected to wires then to a battery and a light bulb. What is the property of the metal that is being tested?
what is Conductivity of electricity
. You are measuring the temperature of air at three points near a lit bulb. The thermometer nearest the bulb is the warmest and the thermometer farthest away is the coolest. Why is this?
what is The bulb radiated heat and the further from the light the more the heat transferred to the room
You place a cold spoon in hot cocoa. After 10 minutes the spoon feels warm and the cocoa has cooled down. What is happening to the thermal energy in the cocoa and the spoon?
what is The cocoa lost thermal energy to the spoon, and the spoon gained thermal energy from the cocoa
You place four materials (metal, wood, plastic, and rubber) in a pot of boiling water. After 10 minutes, the metal was the warmest, the wood was second, the rubber third, and the plastic was the coolest. Which material is the best conductor of heat?
what is metal
Sleeping bags are used to keep warm while sleeping outside in cold weather. What can you infer about sleeping bags?
what is They have insulation
The jar lid on some pickles is stuck. You run the lid under warm water for three minutes and the lid opens right up. How did holding the lid under the water help to open the jar?
what is The warm water caused the atoms in the lid to expand, making it easier to come off
