Convection is when water warms and expands. As the heated water expands, it rises because when a substance is hotter, it is also less dense. When the hotter and lighter water rises and reaches its maximum height, it is the farthest away from its heat source. It is then cooled and becomes more dense, sinking back down towards it's original location. It is usually related to liquids.
Convection is heat transfer in a gas or liquid driven by density differences which cause circulation.
Warm liquids and gases are less dense than could liquids or gasses and the warm liquids or gases therefore rises buoyantly, causing circulating currents which distribute the heat from one place to another.
It is the cycle of heating, rising, cooling, and sinking.
Convection is the transfer of heat by the actual movement of the warmed matter and takes place only in liquids and in gases.
the transfer of heat by currents within a liquid or gas
the transfer of energy as heat through a material
convection is transfer of something when 2 things are placed adjacent to each other .
generally this term is used when we are describing heat transfer process.
cooler air sinks,pushing warmer air upwards. the result is a circulating current of air called convection current
It is physical science because physical science means the study of matter and energy and plastic is matter.
Physical Science is the study of science in the physical world, such as oceanography and electricity.
Medicine is mostly biological science but it has physical science as an active part
Physical Science is the learning of the physical world around you. !
There are a few ideas of the physical science. The main idea of physical science is studying of matter and energy is physical science. Matter is something that takes up space with mass.

A physical science as thermal properties are physical properties.
No earth science is not a physical science because earth science is when it invuolidwith trees and nature physical science is when you deal with gas and fire and iron
