Convection is the heat transfer through atoms or molecules that move, so that's liquids or gases. If you turn a radiator is turned on and the room is full of cool air, the radiator in the middle will warm up the particles above it and as warm things rise these heated particles will rise, pushing the cool air towards the radiator to be heated too.

What is heat transfer that does not cause a temperature change?
Heat transfer that does not cause a temperature change is called latent heat transfer. This occurs when heat is absorbed or released during a change in state (solid to liquid, liquid to gas) without changing the temperature of the substance.
How is heat transfer related to temperature change?
Heat transfer involves the movement of thermal energy from a region of higher temperature to a region of lower temperature. This transfer of heat between objects or substances can result in a change in temperature. The direction and rate of heat transfer is influenced by the temperature difference between the two objects.
What is the difference between specific heat and latent heat, and how do they affect the heat transfer process?
Specific heat refers to the amount of heat required to raise the temperature of a substance by one degree Celsius, while latent heat is the heat absorbed or released during a phase change without a change in temperature. Specific heat affects the temperature change of a substance, while latent heat affects the phase change process. Both specific heat and latent heat play a role in heat transfer processes by determining how much heat is needed to change the temperature or phase of a substance.
What is a sign of heat transfer?
A sign of heat transfer is when there is a change in temperature. Heat will flow from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached. Temperature difference is a key indicator of heat transfer.
Does the change in temperature of an object affect how much heat it can transfer to another object?
The temperature of an object affects how much heat can be transferred. This is because if the object to which heat is transferred has high temperature then there will not be much heat transfer. Heat flows from a body of higher temperature to lower temperature.
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
What is the heat transfer sign convention and how does it impact the analysis of heat transfer processes?
The heat transfer sign convention refers to the direction of heat flow in a system. It impacts the analysis of heat transfer processes by determining whether heat is being gained or lost by a system. This convention helps in understanding the direction of heat transfer and its effects on the system's temperature changes.
When heat is transferred does the temperature always change?
No, when heat is transferred, the temperature doesn't always change. This is because heat transfer can result in either a change in temperature, a change in phase (such as melting or boiling), or a combination of both.
How do you caluculate heat transfer?
(Mass) x (Specific Heat Capacity)*(change in temperature)
What is transient heat transfer?
Transient heat transfer refers to the heat transfer process that occurs over a time period during which the temperature distribution within a system changes with time. This is in contrast to steady-state heat transfer, where the temperature distribution remains constant with time. Transient heat transfer is commonly seen during processes such as heating or cooling of materials, where the temperature changes over time.
What is similar between radiation and conduction?
Both radiation and conduction are modes of heat transfer. Radiation involves the transfer of heat through electromagnetic waves, while conduction involves the transfer of heat through direct contact between materials. Both processes can transfer heat from a higher temperature source to a lower temperature sink.
What is it called When heat flows into an object an the temperature changes?
This process is called heat transfer. Heat transfer occurs when thermal energy moves from a region of higher temperature to a region of lower temperature, resulting in a change in the object's temperature.
