In which form of heat transfer is a medium not required?
Heat transfer by means of radiation doesn't heat the medium. In fact, radiation doesn't even require a medium in order to work. Strictly speaking, convection doesn't heat the medium either. Convection transfers heat by moving the medium around. Of course, heat also spreads throughout the medium by conduction while the convection is going on.
Imagine you put your hand next to one cookie without touching it your hand feels warm by what method has the thermal energy of the cookies transferred to your hand?
All three methods of heat transfer can occur in this case (conduction and convection through the air), but probably the most important one is radiation.
What are three ways heat can travel?
Conduction (through e.g. solid materials like metals that allow heat through - like a saucepan base) It is transformed into another object by touchConvection - in liquids and gases. Hot substances expand and so are less dense than cold substances. These less dense liquids and gases rise and cool ones fall forming a current. as an example, convector heaters in your home, the Gulf Stream that brings warm water from the Caribbean to Europe.Radiation - the method by which energy is transferred through a vacuum e.g. in the infra red heat energy from the sun as it travels across the vacuum of space.radiation, convection and conduction.
How does heat transfer from one object to another through conduction?
Yes, conduction is when two objects are touching. For instance if you touch the stove thermal energy from the stove goes into your hand burning you.
Why is burning your hand on the stove an example of conduction?
Cause the heat had just passed onto you witch made you feel it. Also that means your body is a conductor not an insulator.

Explain why heat doesnt reach your hand by means of convection and conduction?
I can't explain why it doesn't, because it does.Take a 100W incandescent light bulb, lit up.Place your hand a few feet to the side of it; you receive heat by radiationPut your hand a few feet above it; now you get heat by convection as well.Put your hand touching the top; now you get heat by conduction as well.
Is candy melting in a persons hand conduction or radiation?
It is an example of conduction
Heat given off by a fire in a fireplace is an example of - A conduction B Convection C radiation D insolation?
Radiation. Conduction is when one object takes heat from an object adjacent to it, like your hand on a hot plate. Convection is when heat travels through a gas or a liquid to get from one place to another, like a hair dryer to your hair. And Radiation is when heat travels through rays like the sun or a flame. Based on technicalities regarding the question, the flame can heat the surrounding air and travel to you, thus being a convection current.
How is heat transferred between a human hand and a glass of ice tea?
via conduction. there are 3 types of heat transfer: conduction = transfer through direct touch convection = transfer through a liquid or gas radiation = transfer through electromagnetic waves
When your hand melts a snowball What type of heat transfer is it an example of?
convection Du!!!!!!!!!!!! .......
Is hair dryer an example of conduction or convection?
A hair dryer is an example of convection. Convection refers to the transfer of heat through the movement of fluids or gases. In the case of a hair dryer, the heat is generated by an electric element and is then transferred to the surrounding air. The heated air is then blown out of the hair dryer and onto the hair, drying it by convection. Conduction, on the other hand, refers to the transfer of heat through direct contact between objects. An example of conduction would be touching a hot stove and feeling the heat transfer to your hand through direct contact. It is important to note that both convection and conduction can occur simultaneously in many heat transfer situations. For example, a hair dryer may also transfer heat to your hair through conduction as the hot air comes into contact with your hair.
How does conduction travels?
a solid touches another hot solid like your hand touching a hot pan
How is the heat transferred between the hot coffee and the part of the spoon that is in the hot coffee?
Heat will be transferred initially by conduction, which is the direct heat transfer between object (your hand and the liquid). If you leave your hand in long enough, convection will become a major factor. Convection is when currents from a liquid circulate to transfer heat.
What is one real life example for conduction?
CONDUCTION:- Touching a stove and being burned Ice cooling down your hand Boiling water by thrusting a red-hot piece of iron into it
