Give a short answer to the question given below.
Observe the melting and boiling point of the substance A, B and C given in the following table:
| Substance | Melting point (°C) | Boiling point (°C) |
| A | - 210 | - 196 |
| B | 250 | 700 |
| C | - 20 | 90 |
a. State the physical state of substance A, B and C at room temperature (0°C).
i. Physical state of substance "A" is
ii. Physical state of substance "B" is
iii. Physical state of substance "C" is
b. Name the substance which will have more compressibility in the given table, why?
Substance will have more compressibility because gases are compressible than liquids and solids due to the spaces between gas molecules, allowing them to be compressed significantly under pressure.
