One form of heat movement in heated liquids is enjoyed in a domestic boiler cum radiators system. Here the boiler heats the water which is then pumped to the room radiators before being returned to the boiler. The so-called "radiators" are not principally radiators although some heat is radiated from them. More heat is transferred by convection when the hot radiator heats the air next to it.
The classical name for heat transfer in liquids is Convection due to currents within the liquid caused by hotter liquid being less dense than colder liquid.
In times past when houses had a "back boiler" tank connected to a hot water cylinder upstairs it was these convection currents which caused the heated water from the boiler to rise up to the cylinder, and the colder water to descend to the back boiler.
In the case of gases hardly any heat is transferred by conduction or radiation, being transferred almost entirely by convection due to hotter gases being less dense than colder ones.
What else can I help you with?
What type of heat transfer occurs in only liquid and gases?
Convection is the type of heat transfer that occurs in only liquids and gases. It involves the transfer of heat through the movement of the fluid molecules due to differences in their density and temperature.
Movement of heat in a liquid or gas?
Heat can be transferred in a liquid or gas through conduction, convection, or radiation. Conduction is the transfer of heat through direct contact between molecules. Convection involves the movement of the heated material itself, causing a transfer of heat. Radiation is the transfer of heat through electromagnetic waves.
What Heat transfer in liquid and gases caused by the the movement of current?
Heat transfer in liquids and gases caused by the movement of currents is known as convection. This occurs when warmer fluid particles move from areas of higher temperature to areas of lower temperature, carrying heat with them. Convection plays a significant role in redistributing heat within fluids and gases, contributing to the transfer of thermal energy.
What is the the term for heat transfer because of the movement of gas?
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
What are the differences between conduction, convection, radiation, and evaporation in terms of heat transfer mechanisms?
Conduction is the transfer of heat through direct contact between objects, convection is the transfer of heat through the movement of fluids or gases, radiation is the transfer of heat through electromagnetic waves, and evaporation is the transfer of heat through the change of a liquid to a gas.
Which method of heat transfer causes actual movement?
Both conduction and convection. Conduction involves the small movements of individual particles, convection can be on a much larger scale with a hot liquid or gas rising and a cool liquid or gas dropping.
What is the term for heat transfer because of the heat of gas?
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
What is heat transfare in gases called?
Heat transfer in gases is called convection. It is the process by which heat is transferred through the movement of fluid (gas or liquid) particles. Convection occurs when hot air rises and cold air sinks, creating circulation and transferring heat in the process.
What is the term for heat transfer due to gas movement?
The term for heat transfer due to gas movement is convection. In convection, heat is transferred through the movement of fluids, such as gases or liquids, carrying heat from one place to another.
Is the transfer of heat by moving liquid or gas called conduction?
No, the transfer of heat by moving liquid or gas is called convection. Conduction is the transfer of heat through a material without the movement of the material itself.
Conduction in gases and liquid depends on the movement of?
Conduction in gases and liquids depends on the movement of particles colliding with each other and transferring energy through direct contact. In gases, molecules move randomly and collide frequently, transferring heat through collisions. In liquids, conduction occurs similarly as particles in a liquid also collide and transfer heat to neighboring particles.
What is heat transfer by movement of a heated liquidis called?
The heat transfer by movement of a heated liquid is called convection. This occurs when the heated liquid rises due to its decreased density and is replaced by cooler liquid, creating a continuous flow that helps distribute the heat.
