#class8science |Chapter 9 | The_Amazing World of Solutes, Solvents & Solutions | #ncertsolution Exercise Solutions (Keep the Curiosity Alive) *Q1. True/False* i. False – Oxygen is more soluble in cold water than hot. ii. False – Sand and water form a *non-uniform mixture*. iii. False – The amount of space occupied is called *volume*, not mass. iv. False – An unsaturated solution has less solute than a saturated one. v. True – The air is a mixture of gases and forms a solution. *Q2. Fill in the blanks* i. Immersed; rise ii. Solute; solvent iii. Decreases iv. Saturated *Q3.* Correct answer: (ii) Water is denser than oil. *Q4.* Density = 225 g / 90 cm³ = 2.5 g/cm³ → It will sink (since water’s density = 1 g/cm³). *Q5.* Correct: (iii) No more solute can be dissolved into the saturated solution at that temperature. The others are incorrect because they contradict the definition. *Q6.* Bottle capacity = 2 L – 0.5 L = 1.5 L = *1500 mL more water can be added.* *Q7.* Density = 400 g / 40 cm³ = **10 g/cm³**. *Q8.* The unpeeled orange floats because air trapped in its peel decreases its overall density. The peeled one sinks because its density increases Explore the *Amazing World of Solutes, Solvents, and Solutions* from Class 8 Curiosity Science (Chapter 9) in this engaging visual explanation!
