عام ماحول کے دباؤ پر برف کا پگھلنے کا نقطہ ______ ہے؟
Answer: 0 °C
Explanation The melting point of ice at normal atmospheric pressure is 0 °C (zero degrees Celsius). Key Points: 0 K (zero Kelvin) is equivalent to -273.15 °C , which is absolute zero , the lowest possible temperature. 100 °C is the boiling point of water at normal atmospheric pressure.
فاصلہ ایک _____ مقدار ہے۔
Answer: Scalar
Explanation Distance is a scalar quantity because it only has magnitude (amount of length) but no direction. Distance is a measure of how far apart two points are, but it doesn't have a direction.

Answer: Cellulose
Explanation In plants, the cell wall is primarily composed of strong fibers of cellulose , a type of carbohydrate. Cellulose is a polymer of glucose molecules that provides structural support, rigidity, and protection to the plant cell.
Answer: 1.4M
Explanation To calculate the molarity, we need to calculate the number of moles of sodium chloride (NaCl) dissolved in 500 cm³ (or 0.5 L) of solution. Molar mass of NaCl = 58.44 g/mol Number of moles = mass / molar mass = 40 g / 58.44 g/mol ≈ 0.684 mol Molarity = number of moles / volume (in liters) = 0.684 mol / 0.5 L ≈ 1.368 M Rounded to one decimal place , this is approximately 1.4M.
