(a) Water at room temperature is a liquid because it boils at 373 K and the room temperature is nearly . 

The solidification point is It will remain in a liquid state. 

It does not have a definite shape but has a definite volume at room temperature. 

So these are properties of a liquid state.

(b) An iron almirah is a solid at room temperature because it has a definite shape and definite volume. 

So the properties mentioned are satisfied by the solid-state only.

Task 1.3: Let's explore.... On the basis of the above simulation, note composition of each gas, if they are made up of the same etc. or different components .etc. . Make the molecules yourself and observe their 3D models through following PHET simulation; https://phet.colorado.edu/sims/html/build-a-molecule/latest/build-a-molecule_en.html We see that the atom is the smallest component that is making the gases (matter) which may be either present as monatomic (He, Ne, Ar,Xe etc.) or diatomic etc. molecules. Do atoms exist as mono or diatomic molecules only? Write down some examples where atoms have atomicity more than two. Classify the components of air as 'molecules of elements' or 'molecules of compound'. Molecules of elements- Molecules of compound- How do molecules of an element differ from molecules of a compound? Draw the pictures of a molecule of Argon, oxygen, water and carbon dioxide, and label the different types of atoms in the molecule. Atoms in the atmosphere exist in either free or combined state to form different molecules.. Atoms during combination follow certain rules for chemical combination known as law of chemical combinations.
