محلول مادے کی حل پذیری _____ بڑھ جاتی ہے؟
- As the liquid cools down
- As the liquid becomes more concentrated
- As the liquid heats up
- As the liquid becomes more diluted
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- The solubility of a solute substance increases as the temperature of the solvent (liquid) increases.
- This is because heat energy helps to break the bonds between the solute particles and the solvent molecules, allowing more solute to dissolve.
معطلی کی ایک خاصیت کیا ہے جو اسے حل سے مختلف بناتی ہے؟
- Suspensions have dissolved particles
- Suspensions have suspended particles
- Suspensions are homogeneous mixtures
- Suspensions are always transparent
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Suspensions are heterogeneous mixtures that contain particles that are visible to the naked eye and settle out of the mixture over time.
- This is in contrast to solutions, which are homogeneous mixtures that contain dissolved particles that are not visible and do not settle out.
جب کوئی مادہ مائع میں گھل جاتا ہے اور کوئی نیا مادہ نہیں بنتا ہے۔ ان مادوں کو کیا کہا جائے گا؟
- Solute
- Solution
- Compound
- None
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- When a substance (the solute) is dissolved in a liquid (the solvent) and no new substance is formed.
- The resulting mixture is called a solution.
اگر محلول اور محلول کا تناسب زیادہ ہو تو محلول کو ______ کہا جاتا ہے؟
- Aqueous Solution
- Unsaturated Solution
- Concentrated Solution
- Saturated Solution
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- A concentrated solution has a high amount of solute relative to the solvent.
- Indicating that there is a large quantity of the dissolved substance compared to the amount of solvent.

- Liquid-liquid solution
- Solid-liquid solution
- Gas-liquid solution
- Solid-solid solution
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Carbon dioxide (gas) dissolves in water (liquid).
- It forming a gas-liquid solution.
پانی میں لیموں کی تحلیل دراصل ______ کے محلول اور سالوینٹ کے امتزاج کی نمائندگی کرتی ہے؟
- Gas-liquid solution
- Liquid-liquid solution
- Solid-liquid solution
- Solid-solid solution
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Lemon juice, which is primarily liquid, dissolves in water, another liquid, creating a liquid-liquid solution.
- Where both solute (lemon juice) and solvent (water) are in liquid form.
پانی میں نمک کی تحلیل، دراصل _____ کے محلول اور سالوینٹ کے امتزاج کی نمائندگی کرتی ہے؟
- Solid liquid solution
- Solid solid solution
- Liquid liquid solution
- Gas liquid solution
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Salt (a solid) dissolves in water (a liquid) to form a solution.
- Making it a classic example of a solid-liquid solution.
مندرجہ ذیل میں سے کون سا حل کی مثال ہے؟
- Sand and water
- Oil and water
- Sugar and water
- Salt and air
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Sugar and water is a classic example of a solution, where sugar (the solute) is dissolved in water (the solvent).
- The resulting mixture is a homogeneous solution, where the sugar molecules are evenly distributed throughout the water.
مادہ کو تحلیل کرنے والے مادہ کا نام کیا ہے؟
- Solute
- Solvent
- Solution
- Mixture
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- The solvent is the substance that dissolves the solute, typically present in a larger amount than the solute.
- It can be a solid, liquid, or gas, and its molecules or atoms separate the solute molecules or atoms, allowing them to dissolve.
- Examples: water, alcohol, and acetone.
اُس مادہ کا نام کیا ہے جو تحلیل ہو جاتا ہے؟
- Solute
- Solvent
- Solution
- Mixture
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- The solute is the component of a solution that is dissolved in the solvent.
- It can be a solid, liquid, or gas, and it is typically present in a smaller amount than the solvent.
- Examples: sugar, salt, and coffee.
