What is the correct definition of conduction?
1 : the act of conducting or conveying. 2a : transmission through or by means of a conductor also : the transfer of heat through matter by communication of kinetic energy from particle to particle with no net displacement of the particles — compare convection, radiation. b : conductivity.
Which of the following is the correct definition of conduction a the transfer of heat by currents within a liquid or gas b the transmission of heat across Matter C the transmission of heat across empty space d the electromagnetic radiation from the surface of an object which is due to the object’s temperature?
A: The transfer of heat by currents. Explanation: Convection is the transfer of heat by currents, typically within a liquid or a gas.
Which of the following is correct definition of convection?
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.
What is conduction short answer?
The definition of conduction is the movement of something such as heat or electricity through a medium or passage. In electrical conduction, energy is transferred by the movement of electrons or ions.
What are three ways heat is transferred?
Heat can be transferred in three ways: by conduction, by convection, and by radiation.
- Conduction is the transfer of energy from one molecule to another by direct contact.
- Convection is the movement of heat by a fluid such as water or air.
- Radiation is the transfer of heat by electromagnetic waves.
Which is a description of the process of conduction?
Conduction is defined as The process in which heat flows from objects with higher temperature to objects with lower temperature. An area of higher kinetic energy transfers thermal energy towards the lower kinetic energy area.
Which is the best example of thermal conduction?
Conduction is also known as thermal conduction or heat conduction. The coefficient of thermal conductivity shows that a metal body conducts heat better when it comes to conduction. The rate of conduction can be calculated by the following equation: Following are the examples of conduction:
How is conduction related to the rate of heat transfer?
Conduction is also known as thermal conduction or heat conduction. The coefficient of thermal conductivity shows that a metal body conducts heat better when it comes to conduction. The rate of conduction can be calculated by the following equation:
Convection Equation As the temperature of the liquid increases, the liquid’s volume also has to increase by the same factor and this effect is known as displacement. The equation to calculate the rate of convection is as follows: Q = h c ∙ A ∙ (T s – T f)
