You are watching: Two equal masses of two different kinds of matter

Matter- issue is anything i m sorry occupies room and has actually mass is called matter. Air and also water, sugar and also sand, hydrogen and oxygen etc. Matter is comprised of very tiny tiny particles. Corpuscle of matter have room between lock they tempt each other.
2.Classification- top top the communication of physical properties, issue is classified together solids, liquids and gases. ~ above the communication of chemical properties, matter is classified as elements, compounds and also mixtures.
•Solids- Solids have solid molecular force and also a definite shape and size solids deserve to neither flow nor be compressed.
•Liquids- Liquids have weak intermolecular flow and big intermolecular spaces. Liquids perform not have actually a identify shape but can flow.
•Gases- Gases have actually weak intermolecular flow, high compressibility, and no definite shape and also volume.
3.Physical properties of matter- issue is comprised of corpuscle which space very tiny in size. Everything approximately us is comprised of tiny pieces or particles. The corpuscle of matter are constantly relocating (they room in motion).The corpuscle which comprise matter space atoms and also molecules.
4.Interchange in states of matter- issue can adjust its state in solid, liquid or gas relying on the kind of matter.
5.Diffusion- The mix of a problem with one more substance as result of the activity or motion of its corpuscle is referred to as diffusion. It is one of the nature of materials. The diffusion that one problem into an additional substance walk on until a uniform mixture is formed. Diffusion takes location in gases, liquids and solids.
6.Latent heat- Latent warm is the heat energy which needs to be provided to adjust the state of a substance. Latent warm does not increase the temperature of a substance. But latent heat has to be gave in bespeak to change the state that a substance. Implicitly heat can be of combination or of vaporization.
7.Sublimation- The changing of a solid straight into vapours on heating and also of vapours into solid top top cooling, is recognized as sublimation. When these heavy substances room heated, their particles relocate quickly and also they separate completely to kind vapor (or gas). Likewise when these vapor (or gas) is cooled, this particles slow-moving down so easily that they end up being fixed and type a solid.
8.Evaporation- The process of counter of a liquid into vapour (or gas) at its boiling allude is dubbed evaporation. Part particles in liquid always have much more kinetic power than the others. So, even when a liquid is well below its boiling point, few of its particles have actually enough power to rest the pressures of attraction in between the particles and also escape indigenous the surface ar of the fluid in the form of vapour. Thus the rapid moving corpuscle of a liquid space constantly escaping from the fluid to form vapor or gas. Temperature, surface ar area that liquid, humidity, and also wind speed room fators that impact evaporation. Evaporation causes cooling effect.

Effect of change of Pressure: The physics state of issue can also be changed by increasing or decreasing the push to it. Gases have the right to be liquefied by using pressure and also lowering temperature. Once high pressure is applied to a gas, it gets compressed, and when in addition to that we reduced its temperature, it gets converted right into liquid. So, we can likewise say the gases have the right to be turned right into liquids through compression and cooling.
