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
