Definition Of Matter
Matter is anything that has mass and occupies space
More About Matter
- All objects we see with the naked eye are composed of atoms
- This atomic matter is in turn made up of interacting subatomic particles—usually a nucleus of protons and neutrons
- Matter is everything around you
- Matter is anything made of atoms and molecules
- Mass is the amount of stuff in an object
- Matter is sometimes related to light and electromagnetic radiation
- Even though matter can be found all over the Universe, you only find it in a few forms
- Scientists have identified five physical states of matter. Each of those states is sometimes called a phase
- Solids, liquids, gases, plasmas, and one state called the Bose-Einstein condensate (BEC) are the five states of matter
- The scientists who worked with the Bose-Einstein condensate received a Nobel Prize for their work in 1995
- It's about the physical state of the molecules and atoms that make the state of matter
- Matter has been thought to be made of five elements: Air, water, fire, sky and earth
- Everything around us is matter
- Matter was believed to be continuous earlier like a block of wood earlier
- Later on, matter was believed to be made up of particles like sand
- If we dissolve salt or sugar in water, it spreads and occupies space in between the water molecules
- The salt or sugar spreads uniformly in the space in between the water molecules and we get its taste
- When we dissolve salt in water, the particles of salt get into spaces in between particles of water
- There is no change in the level of water
- With this experiment, we can come to the conclusion that matter is not continuous and there is space between particles of matter
- Matter is made of very tiny particles
- This can be demonstrated by dissolving few crystals of KMnO4 in about 100 ml of water.
- Take little solution and dilute it.
- Repeat the experiment
- We can observe that few crystals of KMnO4 can color up to 1 litter of water
Which of the following are not particles of matter?
Answer: -- b & d
2) What produces more severe burns: boiling water or steam?
a) Boiling water
c) Both a & b
Explanation: This is because steam because steam is hotter than boiling water. Because once water reaches a certain temperature it turns to steam so in order for it to just be boiling water the temperature is less than that
3) Matter has how many phases?
Answer: c; they are solid, liquid, gas, plasma and BEC
