Matter around us

Answer

This happens due to DIFFUSION. Perfume particles move from high concentration (spray point) to low concentration areas, mixing with air particles. Gas particles move continuously and have large spaces

Answer

Matter is anything that occupies space and has mass. Examples include water we drink, air we breathe, food we eat, and our body. All substances around us are forms of matter.

Answer

AIR (gas) has large spaces between particles and weak forces of attraction, making it highly compressible. WATER (liquid) has particles closer together with stronger attraction forces, making it nearl

Answer

Evidence: When we dissolve potassium permanganate crystals in water, a small amount colors large volumes of water. This shows matter contains countless tiny particles that spread uniformly throughout

Answer

PROCESS: Salt particles dissolve and occupy the empty spaces between water particles. This proves there are gaps between particles in liquids. The water level doesn't rise because salt fills existing

Answer

Temperature change causes state change. When temperature drops below coconut oil's freezing point, particles lose energy, move slower, and arrange in fixed positions, changing from liquid to solid sta

Answer

1. Definite shape and fixed volume 2. Cannot be compressed easily 3. Particles tightly packed with strong forces 4. Diffusion rate is slowest 5. Particles vibrate in fixed positions Example: Wood, iro

Answer

Two reasons: 1. Gas particles move at very high speeds 2. Large spaces between gas particles allow easy movement. Fewer particles obstruct the diffusion path, making gas diffusion fastest.
