FAQs on Worksheet: Air and Water - 1

1. What are the main properties of air that we need to know for Class 5 Science?
Ans. Air is an invisible mixture of gases including nitrogen, oxygen, carbon dioxide, and other elements that surrounds Earth. It has weight, occupies space, and can be compressed or expanded. Air supports combustion, allows sound to travel, and is essential for respiration in living organisms. Understanding these characteristics helps students grasp why air is vital for life on our planet.
2. How does water change form between solid, liquid, and gas states?
Ans. Water exists in three states: solid ice (frozen below 0°C), liquid water (at normal temperatures), and water vapour or steam (gaseous form above 100°C). The process of melting converts ice to water, while evaporation transforms liquid water into gas. Condensation reverses this by turning vapour back into liquid. These state changes occur due to temperature variations and are reversible physical processes.
3. Why is air important for combustion and what role does oxygen play?
Ans. Oxygen, a crucial component of air (about 21%), is essential for combustion-the process where substances burn and release heat and light. Without oxygen, fire cannot ignite or continue burning. This is why fires go out when smothered with blankets or when oxygen supply is cut off. Understanding this principle helps explain fire safety and why ventilation matters indoors.
4. What's the difference between pure water and salt water in terms of their properties?
Ans. Pure water is tasteless, colourless, and odourless, containing only H₂O molecules. Salt water contains dissolved salts and minerals, making it taste salty and affecting its density and freezing point. Salt water boils at higher temperatures and freezes at lower temperatures than pure water. These differences matter in CBSE Class 5 Science as they show how solutes change water's physical properties significantly.
5. How do we test if air is present in soil and water using simple experiments?
Ans. Air presence in soil can be tested by heating wet soil-bubbles emerge as trapped air escapes. For water, observing bubbles in a glass of freshly boiled water shows dissolved air. These worksheet-based experiments demonstrate that air exists not just around us but also within soil and water bodies. Such practical observations reinforce the concept that air is everywhere in our environment.
