Which best describe the process of convection?
Which best describes the process of convection? Convection is the primary way heat travels through appliances. Convection is the primary way heat travels through liquids and gasses. Convection is the primary way heat travels through rays.
What describes convection process?
Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid.
Which best describes the conduction process?
Which best describes the process of conduction? When two objects touch, the heat is transferred into the air. When two objects touch, the heat from the hotter object is transferred to the cooler object. When two objects touch, the cool air from the cooler object is transferred to the hotter object.
What is convection short answer?
1 : the action or process of conveying. 2a : movement in a gas or liquid in which the warmer parts move up and the cooler parts move down convection currents. b : the transfer of heat by convection foods cooked by convection — compare conduction, radiation.
How does convection process work?
Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink.
What is the process of convection quizlet?
Convection is the transfer of thermal energy by the movement of heated matter. Heating matter causes it to expand and decrease in density. This warmed matter is forced upward as a result of buoyancy. The cooler part of the matter is pulled downward as a result of gravity.
How do convection occur?
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. Convection currents can be seen in lava lamps.
What is convection by Brainly?
Brainly User. When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises.
What is convection with example?
Everyday Examples of Convection radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea – The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting – Ice melts because heat moves to the ice from the air.
Which statement describes convection in the atmosphere?
the statement which best describes convection is that convection occura until all of the fluid is at same temperature. Explanation: there are three forms in which heat is conducted from one body to the other. In sar conduction ,Convection and radiation.
What is process of conduction?
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer to together, than in gases, where particles are further apart.
What causes convection quizlet?
Convection is heat transfer by the movement of currents with in a fluid. It is caused by the difference in temperature and density. Heating and cooling of the fluid, changes in the fluid density, and the force of gravity, combine to set convection currents in motion.
