Heat Transfer and Fluid Flow is a wide subject, worth years of college.

Heat transfer has three modes; conduction, convection and radiation. (Also phase change, not applicable here.)

Most heat transfer in fluids (gases or liquids) is by convection. Depending on conditions, some small amount of conduction and radiation can also be significant.

Which kind of heat transfer can't take place in a vacuum?

Conduction, which is the transfer of heat through direct contact between particles, cannot take place in a vacuum because there are no particles present to transfer the heat.


What is the transfer of heat by currents?

The transfer of heat by currents is known as convection. This process occurs when heat is transferred through the movement of fluids, such as air or water, due to temperature differences. As a fluid is heated, it becomes less dense and rises, carrying heat energy with it, while cooler, denser fluid moves in to take its place.


When Does Heat Transfer Take place?

Heat transfer takes place whenever there is a temperature difference between two objects or systems. This can occur through conduction (direct contact), convection (through a fluid or gas), or radiation (through electromagnetic waves). Heat transfer is a fundamental process in nature that aims to equalize temperature differences.


What is the main way in which heat transfer occurs in liquids and gasses?

The main way heat transfer occurs in liquids and gases is through convection, where heat is transferred through the movement of the fluid itself. As the fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks to take its place, creating a circulating flow that carries heat throughout the system.


What is the transfer of energy from one place to another by the motion of gas or liquid?

This process describes convection, which involves the transfer of heat through the movement of fluids such as gases or liquids. As the fluid heats up, it becomes less dense and rises, carrying heat energy to another location. Conversely, the cooler, denser fluid then moves in to take its place, creating a continuous cycle of energy transfer.

What is heat convection?

Heat convection is the process of heat transfer through a fluid (liquid or gas) due to the movement of the fluid itself. As the fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks to take its place. This creates a circulation pattern that helps distribute heat within the fluid.


Why does transfer of heat not place by conduction in fluids?

Wrong, transfer of heat by conduction does take place in fluids.

Where on the earth does heat transfer take place?

In all circumstances where a material is hotter than its surroundings, heat transfer takes place.


Why does transfer of heat not take place in fluids?

Wrong, transfer of heat does take place in fluids. In fact it can take place more efficiently in fluids than in solids because convection is possible in fluids.

How does convection transfer heat?

Think of a pot of boiling water. The burner makes the heat, the heat rises, and the cold water replaces it, then the cold water gets hotter and rises. It's a cycle


Where does conduction take place in the process of heat transfer?

Conduction takes place in the process of heat transfer through direct contact between objects or substances.


What forms when gas or liquid transfers heat as it moves?

Convection occurs when heat is transferred through the movement of a gas or liquid. As the fluid is heated, it becomes less dense and rises, while cooler fluid moves in to take its place. This creates a continuous cycle of heat transfer.
