Convection is the transfer with in the fluid. If a container of hot liquid is touching something then it is conduction. If the heat is travelling through the air then it is radiation.

What is the transfer of heat by movement of heated liquids or gases?
There are three basic heat transfer mechanisms: Conduction, Convection andRadiation. Heat transfer in opaque solids is just by Conduction. In gases andliquids all three mechanism can contribute to heat transfer.The Convection Mechanism of Heat Transfer is the transportation of heat bythe bulk motion of the fluid. If this motion is produced by buoyancy effects thatarise from the fluid having different temperatures (and so different densities) at different points, it is called Natural Convection. If the motion of the fluid is produced by a pressure gradient (like a fluid been forced to flow through a heated pipe),the heat convection mechanism is called Forced Convection Heat Transfer.
Can a bottle of cologne explode in a hot car?
Depends on how hot. But, yes, it does. If it is hot enough, the gases inside the can will expand to the point of explosion, but it would take quite a bit of heat.
When you burn your finger by touching a hot stove you have experienced heat transfer by what?
There are 4 types of heat transfer, convection, conduction, radiation, and direct flame contact. When you touch the stove the heat is transferred directly from one body, the stove, to the other, the finger. This is heat transfer by conduction.
What happens to hot and cold objects when they brought together?
If heat can flow between them, then heat flows from the hot one to the cold one. The temperature of the hot object falls, and the temperature of the cold object rises. What drives the transfer of heat is the difference in temperature, so as soon as both objects are at the same temperature, the process stops, and no more heat is transferred.
Explain the direction of heat transfer between a mug of hot cocoa sitting in a cold room and explain what eventually happens to the average kinetic energy of the cocoa as a result of the transfer.?
The heat is going from the hot cocoa outwards into the room, as this is an exothermic thing meaning it puts out heat. The average kinetic energy will be lower than original simply because there is less heat.
What method of heat transfer removes heat from hot liquids?
Convection :p
What is the transfer of heat by hot liquids and gasses?
i ave no idea
What is the job of a thermos?
To keep hot liquids hot and cold liquids cold by minimizing heat transfer between the inside of the thermos with the outside.
What can cause a chemical burn?
Heat causes thermal burns. Contact with Flames, hot objects, hot liquids, hot gases, or the fireball from an explosion will result in a thermal burn.
What are the types of heat transfers?
Conduction: Transfer of heat in solids Convection: Transfer of heat in liquid and gases (convection currents are the motion of which the heat travels in, see hot air balloon's) Radiation: Transfer of heat through vacuum (space i.e no particles)
What is produced when gases or liquids rise in a circular path due to termperature differences?
Motion of a fluid owed to a difference in temperature within the fluid is calledThermal Convection. The result of this phenomenon is a transfer of thermalenergy (heat), from a hot body to a cool body.
What is the difference between sensible heat gain and latent heat gain?
When an object is hot, the temperature rises as heat is added. This increase in heat is called sensible heat. Solids can become liquids and liquids can become gases but changes like this require the addition or removal of heat. The heat that causes these changes is called latent heat.
What is a hot liquid called?
its pretty much selfexplanitory, its fluids (liquids and or gases) that are hot.
How does vacuum flasks keep hot liquids hot and cold liquids cold?
by inhibiting heat conduction
What is hot to cold?
hot to cold is heat transfer
What are some of the features of a thermos bottle that makes it a good container for keeping cold liquids cold and hot liquids hot?
The insulation of a thermos slows the transfer of heat into or out of it. So if there is a hot liquid inside, it cools down more slowly, and if there is a cold liquid inside, it warms up more slowly.
What is the directinality of heat transfer?
From "hot" to "cold".
