Which type of heat transferred involve heat flow from hot objects to colder objects?
Convection and Conduction. Convection is the movement of hot gas to areas where it is colder, and conduction is the direct transfer of heat from a hot object to another object that is touching it.
When a hot object is placed in contact with a cooler object the hot object warms a cooler one can you say it loses as much temperature as the cooler one gains?
No. One object will lose as much HEAT as the other gains. The change in temperature, on the other hand, will depend on the masses involved and on their heat capacity. It is even possible that one object's temperature reduces, while the other doesn't increase at all - for example, when ice melts.
Does hot air rise in a vacuum?
No. A vaccum cannot have any air in it, or it isn't a vacuum
What happens to the temperature of an object when it loses heat energy?
The temperature of an object decreases when it loses heat energy because heat is a form of energy that flows from hot to cold objects. As heat energy leaves the object, its molecules lose kinetic energy and slow down, resulting in a decrease in temperature.
Does heat travel from a hot object or cold object?
Heat always travels from a hot object to a cold object. This is based on the second law of thermodynamics, which states that heat naturally flows from regions of higher temperature to regions of lower temperature in an attempt to reach thermal equilibrium.

How does wind affect cooling?
Heat from an object will disipate into the atmosphere, if the atmosphere is really cold, the object will lose heat faster than when it is hot. Wind removes the immediate hot air from around an object, thus creating a cooler environment around it, allowing for quicker cooling. The moving air will also evaporate moisture off of an object which will take heat away from that object.(latent heat of vapourisation).

How does a vacuum bottle-double walled keep an object hot or cold?
By preventing the exchange of heat between the contents and the outside environment through the container's walls.
Why object coll when heat is removed?
Because the object becomes hot when heat is added.
Does heat travel from a hot object or cold object?
Heat always travels from a hot object to a cold object. This is based on the second law of thermodynamics, which states that heat naturally flows from regions of higher temperature to regions of lower temperature in an attempt to reach thermal equilibrium.
When a hot object touches a cool object the particles in the hot object cause the particles in the cool object to?
transfer heat energy from the hot object to the cool object until they reach thermal equilibrium.
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 for heat to be transferred by conduction. Conduction is the process of heat transfer through direct contact between particles of a substance. Heat flows from the hotter object to the colder object until thermal equilibrium is reached.
If touch a hot object you feel the heat due to?
When you touch a hot object, you feel the heat because heat energy is transferred from the object to your skin. This increase in temperature activates pain receptors in your skin, triggering a sensation of heat or pain. Your body then reacts by moving away from the hot object to avoid further damage.
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.
