Matter.
yes indeed solids can flow as well. all states of matter are fluids.
A gas can flow from one place to another. Liquids can also flow, but solids cannot flow because their particles are closely packed and do not move freely.
The three states of matter are solid, liquid, and gas. In a solid, particles are tightly packed and vibrate in place. In a liquid, particles are more spread out and can flow. In a gas, particles are far apart and move freely.
heat flow and waves
When an animal eats a plant as food, both energy and matter are passed from one organism to another in a food web. Unlike the flow of energy in a food web, however, the flow of matter is not one way. Matter cycles within a community.
Fluids have the ability to flow. Fluids are Liquids and Gasses.
Energy flow refers to the transfer of physical energy from one place to another. This often involves the flow of fluid.
Simply, there are three types of matter (which scientists call states), solid, liquid and gas. Liquids and gasses can flow. Solids do not. The solid state is defined by the fact that solids can not flow.
Currents are a "flow" of water from one place to another.
