A method which is used to separate coloured chemicals or substances, especially dyes is known as?

A Filtration

B Sublimation

C Paper chromatography

D Distillation

Explanation

Explanation
Chromatography is one of the latest techniques , which is used to separate the colored components of a mixture . Ink is a mixture of several dyes therefore we can separate those colors from one another using chromatography . **** ND20-1-2023

Explanation
The smallest particle of a compound is called a molecule . Molecules are formed when atoms of the same or different element s combine. while The matter is made up of the smallest particles called atoms *** ND20.1.2023

Explanation
In a solid state, particles cannot move from their position. They can only vibrate at their mean position . The particles in solids vibrate about fixed positions; even at very low temperatures. *** ND18-1-2023

Explanation
The nucleus is primarily composed of protons and neutrons, collectively called nucleons . protons and neutrons, both types of particles reside inside the nucleus of an atom *** ND18-1-2023

Explanation
non-magnetic materials are examples Rubber plastic stainless steel feather paper mica gold Silver leather *** ND18-1-2023

Explanation
The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. *** ND18-1-2023

Explanation
When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached. *** ND18-1-2023

Explanation
Producers, also known as autotrophs. They are organisms that can produce their own food through photosynthesis, using water (H2O), carbon dioxide (CO2), and sunlight to produce glucose and oxygen.

Explanation
The correct answer is: Gases have definite volume Gases: Have indefinite shape Have indefinite volume Can be compressed

Explanation
If an opaque object is moved closer to the light source, the shadow gets bigger. This is because the light source appears larger and more intense from a closer distance, casting a larger shadow.
