What are three ways heat can travel?

Answer 1

Conduction (through e.g. solid materials like metals that allow heat through - like a saucepan base) It is transformed into another object by touch

Convection - 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.

Answer 2

Three ways heat can travel is Radiation,Convection ,Conduction.

1- Radiation:-

It doesn't require any medium. The best example of radiation is heat travelling from Sun to Earth.

2- Convection:-

Convection requires a liquid medium. It's best example is the heating of water in a beaker.

3- Conduction:-

It requires a solid or material medium. The heat is transferred by the vibration of molecules for example the heating of a metal rod after putting candle on the other side.

Answer 3

Conduction, Convection and Radiation

For example, for conduction you can use a boiling pot of water.

For convection you can use a blender.

For radiation you can use the sun or another one is your cell phone.

Answer 4

• Convection, warm water or air or any other gas or fluid, rises cold falls and a heat source creates the system. (Ice water in a glass on a warm day)
• Conduction, cold object touches hot (My hand and my frying pan last night)
• Radiation is when you can feel the heat coming off something with out touching it (the sun is a good example)
