Convection occurs mainly in the gaseous state, where heat is transferred through currents in air. Convection can also occur in liquids, however it is generally identified with gases.
gas and liquid
What else can I help you with?
Describe the process of convection?
Convection is caused by temperature differences, in a gas such as air, which affect the gas density in local areas thus causing movement of the gas, generally upward due to buoyancy of warmer gas compared to the average density. Thus heat from a heating element near the floor of a room can be spread through the room without any forced circulation.
What are three ways that heat transfers from hot objects to cool objects?
The three ways are: radiation, conduction, and convection.
How many types of heat transfer are there?
Three. Conduction, convection and radiation.There are three ways heat can be transferred. Two ways include convection and radiation. The third way is conduction.
A kite rises high above a hot sandy beach is an example of what kind of heat transfer?
thermal-type: radiation source: http://quizlet.com/2000966/heat-thermal-energy-states-of-matter-flash-cards/
The study of matter and changes that occur in matter best describes the science of?
Chemistry
What two states of matter can occur in convection?
Convection currents are in the liquid and gas states.
In which of the three states of matter does convection occur?
liquids and gases
Wich types of heat transfer take place only in matter?
Conduction and convection are types of heat transfer that occur only in matter. Conduction is the transfer of heat through direct contact between particles, while convection involves the movement of heated matter, such as air or water, transferring heat from one place to another. Radiation, on the other hand, can occur in a vacuum because it does not need a medium to transfer heat.
Is matter needed for convection?
Yes, matter is needed for convection to occur. Convection is a heat transfer process that involves the movement of matter, typically a fluid like air or water, due to differences in density caused by temperature variations. Without matter to transport the heat, convection cannot take place.
What 2 types of materials will convection most likely occur?
Convection is most likely to occur in fluids, such as liquids or gases, due to the movement of their particles. Additionally, convection can also occur in certain solids that are capable of flowing, such as molten lava or heated metals.
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
Why does the energy from the sun travel to Earth by radiation instead of by convection or conduction?
Energy from the sun travels to Earth by radiation because space is a vacuum and there is no medium for convection or conduction to occur. Radiation is the most efficient way for heat to transfer through the vacuum of space.
What is more likely to occur in the water thermal energy transfer by conduction or convection?
Convection
In which layer of earth does convection occur?
mantle
What is a good sentence for convection?
Convection is the movement of matter due to differences in density.
Where can a divergent boundary occur?
They occur when the convection currents are less dense and rise.
What two types of of heat transfer occur in a space heater?
In a space heater, conduction and convection are the two types of heat transfer that occur. Conduction transfers heat through direct contact between the heater's heating element and the surrounding air or objects, while convection involves the circulation of heated air in the room due to the warm air rising and cool air sinking.
