Which describes the transfer of heat through matter by activity of molecules?
Answer. The process that describes the transfer of heat through matter by activity of the molecules would be conduction. This type of heat transfer due to the motion of electrons and ions. within a body. As molecules collide with each energy is transferred and released which cause temperature to rise or drop.
What is heat transfer?
the transfer of heat through matter by molecular activity. Nice work! You just studied 33 terms! Now up your study game with Learn mode.
What are three mechanisms of energy transfer as heat?
Three mechanisms of energy transfer as heat are conduction, convection, and radiation. Conduction is the transfer of heat through matter by molecular activity. Convection is the transfer of heat by mass movement or circulation within a substance.
What type of energy transfer occurs when you walk on hot sand?
Radiation, Conduction, Convection. Describe the types of energy transfer that occur when you burn your bare feet when walking on hot sand. Radiation heats the sand, but the direct contact transfer of this energy to the bare foot is conduction.
Is the transfer of heat by molecular collisions?
This type of heat transfer is called convection.
What is the name of the transfer of heat through a substance by mass movement?
Convective heat transfer, or simply, convection, is the transfer of heat from one place to another by the movement of fluids, a process that is essentially the transfer of heat via mass transfer.
Is heat a molecular movement?
Heat is the energy an object has because of the movement of its atoms and molecules which are continuously jiggling and moving around, hitting each other and other objects.
What process describes the transfer of heat by the movement of the air?
When heat is transferred through air it is called? Convection: Convection is the transfer of heat from a surface by means of a fluid such as air. Natural convection occurs as air is heated: it expands rises and is replaced by cooler air.
How is heat transferred in the activity?
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.
What is convection process?
convection, process by which heat is transferred by movement of a heated fluid such as air or water.
What is molecular movement?
Molecular movements are required to provide various essential molecules throughout the body of an organism for repairing and maintaining their structure. Molecular movements are those movements which we cannot observe from naked eyes but play an important role in all the life processes.
What is molecule movement?
Molecular motion is defined as the movement of constituent particles or molecules in a certain direction. The molecular motions are affected by heat and temperature. This is because the temperature is the measurement of the average kinetic energy of the molecules and represents the motion of molecules.
What is the molecular movement of a solid?
gas vibrate and move freely at high speeds. liquid vibrate, move about, and slide past each other. solid vibrate (jiggle) but generally do not move from place to place.
What is conduction and convection?
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas.
How does convection transfer heat?
Convection. Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.
When heat is transferred through gases it is called?
Convection transfers heat energy through gases and liquids. As air is heated, the particles gain heat energy allowing them to move faster and further apart, carrying the heat energy with them.
