- acid अम्ल
- A substance that tastes sour, like lemon juice or vinegar. It turns blue litmus red.
- ChemistryEnvironment
- base क्षार
- The opposite of an acid, like soap or baking soda solution. It feels slippery and turns red litmus blue.
- Chemistry
- carbon dioxide कार्बन डाइअक्साइड
- A gas we breathe out. Plants take it in to make their food.
- ChemistryBiologyEnvironment
- condensation सघनन
- When a gas cools and turns back into a liquid, like drops on a cold glass.
- ChemistryEnvironmentPhysics
- density घनत्व
- How much mass is packed into a space. Things less dense than water float.
- PhysicsChemistry
- dissolve घुल्नु
- To mix into a liquid so completely that you can no longer see the pieces.
- ChemistryEnvironment
- evaporation वाष्पीकरण
- When a liquid slowly turns into a gas (vapour), like puddles drying in the sun.
- ChemistryEnvironmentPhysics
- evidence प्रमाण
- What you saw or measured that shows whether an idea is right.
- PhysicsChemistryBiologyEnvironmentTechnology
- fair test निष्पक्ष परीक्षण
- A test where you change only one thing, so you know what caused the result.
- PhysicsChemistryBiologyEnvironmentTechnology
- filtration छान्ने विधि
- Separating solid bits from a liquid by pouring it through filter paper or cloth.
- ChemistryEnvironment
- indicator सूचक
- A substance that changes colour to show whether something is an acid or a base.
- ChemistryEnvironment
- mass पिण्ड
- How much matter something has, measured in grams or kilograms. It is the same everywhere.
- PhysicsChemistry
- mixture मिश्रण
- Two or more substances mixed together, which can be separated again.
- ChemistryEnvironment
- neutral तटस्थ
- Neither an acid nor a base, like pure water.
- ChemistryEnvironment
- oxygen अक्सिजन

- ChemistryBiologyEnvironment
- particle कण
- A tiny piece that matter is made of, far too small to see.
- ChemistryPhysics
- prediction अनुमान
- What you think will happen before you try it. It is fine if it turns out wrong.

- sediment थिग्रिएको
- Heavy bits that sink and settle at the bottom of a liquid.
- ChemistryEnvironment
- solute घुलित
- The substance that dissolves, like the salt in salt water.
- Chemistry
- solution घोल

- ChemistryEnvironment
- solvent घोलक
- The liquid that something dissolves in, like the water in salt water.
- Chemistry
- temperature तापक्रम
- How hot or cold something is, measured in degrees Celsius (°C).
- ChemistryPhysicsEnvironment
