Questions based on matter and its properties:
Q1. what is matter
Ans:Matter is anything which occupies space and has mass.
eg-pen,paper,water droplet,air etc

Q2.Explain an activity to show that particles of matter have space between them
Ans:
Q3. What are the properties of matter?
Ans: The properties of matter are as follows:
1. Matter is made up of particles.
2. Particles of matter are very very small.
3. Particles of matter have space between them.
4. Particles of matter move continuously.

Q4.What is diffusion? 
Ans: It is defined as the movement of particles of matter from higher concentration to lower concentration.
eg- when we burn incense stick its gaseous particles mix with the particles of air on their own and as a result we get the fragrance in the whole room.

Q5.How does temperature effect the rate of diffusion?
Ans:The particles of matter possess kinetic energy and when we increase the temperature the kinetic energy also increases and as a result the particles start moving rapidly,thus increasing the rate of diffusion.

Neem and Rheumatoid Arthritis

 Neem, scientifically known as Azadirachta indica, has been used in traditional medicine systems, such as Ayurveda, for various health conditions, including rheumatoid arthritis. While neem is not a cure for rheumatoid arthritis, it does have some properties that may be beneficial for individuals with this condition: 1. **Anti-Inflammatory Properties:** Neem contains compounds like nimbidin and nimbin, which have anti-inflammatory properties.

Question Answers of matter in our surrounding

Q1 . How melting point of a substance indicates the strength of of its intermolecular forces of attraction Ans: More strong is the force of attraction more energy is required to break 20 forces of a fraction hence the substance which has high melting point indicates that its particles are tightly packed. Q2. Suggest a method to liquefy gases Ans: By applying pressure and reducing temperature. Q3. Define latent heat of vaporization Ans: latent heat of vaporization is defined as the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point. Q4. Define latent heat of fusion Ans:It is defined as the heat required to change 1 kg of solid to liquid at its melting point. Q5. When a solid melts its temperature remains the same so where does the heat energy go? Ans: During the experiment of melting the temperature of the system does not change even after the melting point is reached till all the ice melts. This happens even though we contin...
