Question 23 of 25intermediate🔍 AnalyzeShort Answer2 marks

Identify more such objects and write names of at least three of them.

Correct Answer

Three objects that could be confusing when classifying as solid, liquid, or gas are:

1) Sand - It is made of tiny solid particles but flows like a liquid.

2) A sponge - It is solid but contains air pockets (gas) inside it.

3) Clouds - They appear solid but are actually made of tiny water droplets (liquid) suspended in air.

Other examples include foam (solid with gas bubbles), jelly (solid-like but contains liquid), and fog (appears solid but is tiny water droplets in air).

Explanation

Activity 6 on Page 12 asks students to classify objects as solids, liquids, or gases. The chapter notes that some objects like sand, sponge, and clay can be confusing. Sand is made of solid particles but flows; sponge is solid but contains air; clay can be moulded like a liquid but is actually solid. These examples show that classification can sometimes be complex.
