Everyday Examples of Convection
radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea – The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting – Ice melts because heat moves to the ice from the air.
Which is an example of conduction quizlet?
Conduction is the direct heat transfer from one substance to another. Example of Conduction: Ice melting in your hand . Convection is the direct heat transfer from a fluid.
Which is an example of convection quizlet?
An example of convection is heating a pot of soup on a stove . As soup at the bottom of the pot gets hot, it expands and becomes less dense. The warm, less dense soup moves upward, floating over cooler, denser soup. At the surface, the warm soup spreads out and cools, becoming denser.
What is convection science quizlet?
Convection. the transfer of heat by movements of a fluid . Radiation . the transfer of heat through space .
Is holding hands an example of convection?
That's how the heat from the Sun reaches the Earth, or how heat from the radiator warms your hands even if you don't touch it. But if you hold your hands above the radiator it will feel hotter than if you hold them to the side. ... This way of transferring heat is called THERMAL CONVECTION.
What are the 10 examples of convection?

What are 2 examples of conduction?
- You can warm your back muscles with a heating pad. ...
- The heat from a hot liquid makes the cup itself hot. ...
- If you are cold and someone holds you to warm you, the heat is being conducted from their body to yours.
What are examples of conduction around your house?
Conduction: Touching a stove and being burned . Ice cooling down your hand . Boiling water by thrusting a red-hot piece of iron into it .
What is convection quizlet a cycle?
Convection is a cycle of moving material formed by the rise of less-dense material and the sinking of denser material . ... In general, warmer materials are less dense, and colder materials are more dense.
Which is the best definition for conduction?
1 : the act of conducting or conveying . 2a : transmission through or by means of a conductor also : the transfer of heat through matter by communication of kinetic energy from particle to particle with no net displacement of the particles — compare convection, radiation.
What is a convection current quizlet?
Convection currents are the transfer of heat through the Earth's magma . They can be found in the mantle. The hottest part of the Earth is the core. the heat from the core is transferred into the lower mantle. ... As the magma reaches the upper Mantle, it reduces in temperature and begins to become more rigid.
Which of the following defines convection?
Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection is a major factor in weather. ... That current can result in wind, clouds, or other weather.
Which best describes the shape of a convection current?
The shape of a convection current would be circular . Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over.
Is rubbing an example of conduction?
| A B | putting your cold hand on a warm surface conduction | drying your hair with a hair dryer convection | heating your cold hands with your warm breath convection | rubbing your hands together and creating heat conduction |

Is eggs cooking in a frying pan conduction convection or radiation?
Heat is transferred by conduction, convection, and radiation . Conduction is heat transfer by direct contact, like frying an egg.
Is steam from a cup of tea conduction convection or radiation?
You pour a cup of steaming tea from a teapot. Your teacup is warm to the touch. Somehow, heat was transferred from one object (the cup) to another (your hand) that it was touching. This is an example of conduction , one of three ways that heat can be transferred.
