${\huge{\blue\longrightarrow{\texttt{\orange Q\red U\green E\pink S\blue T\purple ION\red}}}}$
Give two reasons to justify—
1) water at room temperature is a liquid.
2) an iron almirah is a solid at room temperature.​
​

Answer 1

Answer:

An iron almirah is a solid at room temperature.

An iron almirah is a solid at room temperature (25°C) because: It has a definite and rigid shape and. Fixed volume like a solid at room temperature.

Answer 2

$\huge\sf\underline{Answer}:$

ANS :- 1 . = (A) Water at room temperature exists as liquid because its melting point is below room temperature while boiling point (100º C) is above room temperature.

Similarly, (i) A fixed mass of water occupies a fixed volume

ANS - 2 =

1) As almirah is a solid, so it has a definite shape and volume. so it is solid at room temperature.

2) the melting point of iron is very high (1538°) while the room temperature is 28°. as melting point of iron is very high as compared to room temperature, it is solid at room temperature
