Cooling or Heating
First of all we have 3 phases, Gas, Liquid and Solid
to change from gas to liquid to solid, cooling is required
and to change from solid to liquid to gas, heating is required
This type of heat is called latent heat, always think of water as an example
Ice --> Water , heating
Water--> Water Vapour, more heating
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
mass cannot change quanity if it is not added or removed
Dividing an object's change in position by the time it took to make that change gives you the average velocity of the object. Velocity is a vector quantity that includes both speed and direction, so it's important to consider both aspects when calculating velocity.
* Water and lava are the make a shape but they are not one
The smallest part of matter that still functions like matter is called an atom. The atoms make up molecules that in turn make up cells.
The four phases of matter are solid, liquid, gas, and plasma. Each phase is characterized by the arrangement and movement of particles that make up the substance.
The purpose is to avoid pollution and to make economies of materials.
They believe change is necessary to make society more equal.
No, it won't
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
The seven phases of matter are amorphous solid, crystalline solid, vapor, liquid, compressible liquid, gas, and supercritical fluid. Each phase is formed as a particular temperature and pressure.
Solids are one of the four phases of matter (the others being liquid, gas, and plasma). Solid particles are densely packed and rigid, making them have a definite shape unlike the other phases of matter. They have little space to move which is why it is hard for you to make your hand pass through a table. They also do not pressurize well.
The three phases that make up interphase are G1, S, and G2.
it puts force on an object to make it move and makes matter change
A change in the composition of matter occurs during every chemical reaction. This involves the breaking and forming of chemical bonds, leading to the rearrangement of atoms to create new substances with different properties.
If by matter you mean molecules / atoms then no. Physical change is when the look / shape of something is changed but not its chemical structure, chemical change is when the molecules that make up the object n question are changed.
The commonly known 4 stages of matter in order from coldest to hottest are "solid," "liquid," "gas," and "plasma." However, some scientists now believe that there is a 5th stage which is at cooler temperatures than the "solid" stage. This stage is, at present, refered to as "atom stuff" --a funny name for a supercooled metal, considering the work the went through to get it that way, i know, but that's what they call it. Sooner or later, it is still possible that they will change this name to something cooler.
