In order for heat to be transferred by conduction which of the following must occur A cold object must be heated with hot air. A hot object must be directly touching a cold object. The Sun must heat t?
A hot object must be directly touching a cold object.
When is one object hotter than another?
When one object is hotter than another, heat will be transferred from the hot object to the cold object. The hot object will cool down, and the cold object will heat up, until they are the same temperature.
Can cold energy be transferred to an object?
no, cold energy cannot be transferred into an object because you need heat in order to form an object for the celcuims
How heat is transferred between a hot and a cold object by conduction?
because when something hot touches something cold the heat touches the surface of the cold thing making it burn and spread the heat around making it warm.
Does heat travel from a hot object or cold object?
heat travel from a hot object first then to cold object!
What term describes how hot or cold an object is?
What term describes how hot or cold an object is?
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.
What is more dense a cold object or a hot object?
A cold object is more dense.
Why does cold water warm up when added to hot water?
Heat energy is transferred from the hot water to the cold.
What happens to the thermal energy the particles in steam have when it comes into contact with your skin?
In general, when a hot object comes in contact with a cold object, heat (thermal energy) is transferred from the hotter to the colder object.
What makes an object hot or cold?
We perceive an object as hot or cold according to how fast its particles are moving. The faster they move, the hotter the object.
The greatest amount of heat energy transferred between the hot and cold water is transferred by the process of?
absorption
