Give Two Reasons to Justify A) Water at Room Temperature is a Liquid B) An Iron Almirah is a Solid at Room Temperature

Answer: Because of the presence of hydrogen bonds, water is liquid at ambient temperature. For fractions of a second, these connections hold water molecules together. Water molecules are constantly moving. There is random movement of gaseous molecules. When water molecules join together due to hydrogen bonding, they stick together for a brief but considerable period of time.

At room temperature (25°C), an iron almirah is solid because:

• It has a distinct and hard form.
• At room temperature, the volume is fixed, as if it were a solid.
• The shape does not deform when external force is applied.
