What term describes the disorder of random molecular motion?
Brownian motion describes the disorder of random molecular motion, which is caused by the collision of molecules in a fluid. This phenomenon was first observed by botanist Robert Brown in 1827.
What are convection currents created by?
Convection currents are the flow of fluid (liquid or gas) caused by the molecular motion resulting from the transfer of heat through the fluid. In meteorology it is the vertical movement of atmospheric gases caused by heat, atmospheric pressure, condensation of water vapor, and other factors.
Absolute zero may be regarded as the temperature at which?
molecular motion ceases, meaning there is no heat energy remaining to transfer. It is the lowest possible temperature on the Kelvin scale, at approximately -273.15 degrees Celsius or 0 Kelvin.
How many general methods of energy transfer are there?
There are three general methods of energy transfer: conduction (transfer through direct contact between objects), convection (transfer through fluid motion like air or water currents), and radiation (transfer through electromagnetic waves).
A substance can absorb heat energy by the process of?
There are three methods by which substances absorb heat. These are conduction, or heat transfer through contact, convection, or heat transfer through fluid motion, and radiation, or heat transfer through electromagnetic radiation.
What is the definition of a Convection cell?
The transfer of heat through a fluid (liquid or gas) caused by molecular motion.
What is the transfer of heat through a fluid (liquid or gas) caused by molecular motion?
Convection is the transfer of heat through a fluid (liquid or gas) caused by molecular motion. As the fluid is heated, its molecules move faster and spread apart, becoming less dense. This creates convection currents that transport heat throughout the fluid.
What does convection mean in science terms?
convection is the transfer of heat in a liquid or gas by thermal energy from one part of a fluid to another. ;0)
The transfer of heat by direct atomic or molecular kinetic motion?
Conduction is the transfer of heat by direct atomic or molecular kinetic motion, typically occurring in solids or stationary fluids. This process involves the transfer of thermal energy from a higher temperature region to a lower temperature region through direct physical contact between the particles.
The direct transfer of molecular motion through solids?
This process is called conduction. It occurs when molecules collide, transferring kinetic energy from one molecule to another within a solid material. Conduction helps distribute heat evenly in solids like metals and is governed by the material's thermal conductivity.
What is the transfer of thermal energy through the motion of particles caused by temperature differences?
Conduction is the transfer of thermal energy through the motion of particles, caused by temperature differences. It occurs in solids, liquids, and gases when atoms or molecules collide with each other, transferring heat energy.
Is a heat considered a matter?
No. Heat is a measurement of molecular motion caused by energy.
Is heat considered a type of matter?
No. Heat is a measurement of molecular motion caused by energy.
What term describes the disorder of random molecular motion?
Brownian motion describes the disorder of random molecular motion, which is caused by the collision of molecules in a fluid. This phenomenon was first observed by botanist Robert Brown in 1827.
Which term describes the describes the disorder of random molecular motion?
entropy
What is a great sentence for convection?
Convection is defined as the transfer of heat through a fluid,(liquid, or gas form) caused by motion of molecules. A pot of water on the stove, warms through the process of convection.
Convection is the transfer of heat through what?
Convection is "the transfer of heat through the motion of molecules in a fluid."
