Question

What is the physical state of water at 14°C.​

Answer 1

Answer:

What is the physical state of water at (a) 25°C (b) 0°C (c) 100°C ?

Answer:

What is Matter?

The matter is anything that has mass and occupies space.

The three basic states of matter are solid, liquid and gas.

Water

We know that water exists in all three states of matter.

Water exists as ice in solid form, as water in liquid form, and as vapour in gaseous form.

These interconversions of states of matter are visible to a common man in his day to day life.

So, let us see at what suitable temperature water exists in all these three forms:

(a) 25 º C

Water at 25°C is present in the liquid state.

The water which we use for our day-to-day activities is in a liquid state.

The water we use for drinking, cooking, washing, etc., all are in a liquid state.

(b) 0ºC

At 0°C, water exists in solid-state.

We know that the freezing point of water is 0 °C.

The liquid form of water starts to become solid (ice) at this temperature.

Example: If you keep an ice cube tray filled with water and freeze it for a few hours, you may observe the cubes where you poured water have become solid. Ice is the solid state of water.

(c) At 100ºC

At 100°C, water exists in a gaseous state.

We know that the boiling point of water is 100°C.

The water starts to evaporate after attaining this high temperature.

Example: When you boil water in your home, you observe the vapours coming out of the vessel after some time. These vapours are the gaseous state of water.

Answer 2

Answer:

liquid is the physical state because water becomes ice only at 0⁰c and steam at 100⁰ c
