In this Mission Mid-Terms series, your favourite BYJU’S teacher, Kriti Ma’am, discusses some important concepts in your class 9 Science chapter 1, Matter in Our Surroundings.

Some of the topics covered in this chapter are as follows:
- Physical Nature of Matter
- Characteristics of Particles of Matter
- States of Matter
- Evaporation

The matter is made up of small particles. The matter around us exists in three states— solid, liquid and gas. Evaporation is a surface occurrence. Particles from the surface gain enough energy to overcome the liquid's attraction forces and transition to the vapour state. Join this class to learn more about Matter in Our Surroundings.

Congratulations everyone for passing 8th class and entering in 9th class😀😊😊

[azwaaslam]

Legends watching this session the day before exam😂 Thank you sooo much bujus🙌

[tarndeepkaurvirdi]

Characteristics of matter are
1.They attract each other .
2.They are continuously moving.
3.They have space between them .

[shreyanmuppala]

Thank You Ma'am for explanation and notes it really helped!

[ravindrajaybhaye]

Legends are watching in summer vacations 🌅

[navyadhanta]

Good morning mam my name is navya dhanta . Important question🙋

[Lalbisht]

Diffusion is high concentration to low concentration

[krocs-ls]

2.particles of matter have spaces between them
3.particles of matter attract
4.particles of matter are constantly moving

[its_pranay]

Ex for diffusion is like dissolved sugar in water and the water level do nt rise as particles have intermolecular space between thrm.

a baloon when blown increases its vlume because the particles inside the baloon is pushing it to strech

[its_pranay]

49:14 Thank you so much for this wonderful and beyond our imagination session🌠🔮✨💎👍🏻

[ishika-preet]

Mam what is difference between boiling point of liquid and condensing point of vapour???

[its_pranay]

33:22 total heat given/heat produced by 1 kg

[mekadheerajnarayana]

thanks mam for helping me with my lesson i think i will pass in the exam

😄💯

[_evolution]

MATTER is something which has mass and occupies space

[idhayarahul]

What are the different between vaporization and evaporation

[kreweypie]

Thank you ma’am, it was a clear and slow session, I understood everything :))
Answer: 298 K

[its_pranay]

Yes matter can change its shape.
Ex : Ice

[madhumathisanchi]

Which don't need space and mass are non matters

[haseenamusthafa]

Guys this teacher is very sweet🥰.... But, The problem is she is very lagging....
