State four physical properties of water
Answers
Answer:
i am so thank ful to answer your question.
Explanation:
Because water seems so ubiquitous, many people are unaware of the unusual and unique properties of water, including:
Boiling Point and Freezing Point.
Surface Tension, Heat of Vaporization, and Vapor Pressure.
Viscosity and Cohesion.
Solid State.
Liquid State.
Gas State.
Hope it helps
Answer:
The physical properties of water are:-
> Water has a high specific heat. Specific heat is the amount of energy required to change the temperature of a substance. Because water has a high specific heat, it can absorb large amounts of heat energy before it begins to get hot. It also means that water releases heat energy slowly when situations cause it to cool. Water's high specific heat allows for the moderation of the Earth's climate and helps organisms regulate their body temperature more effectively.
> Water in a pure state has a neutral pH. As a result, pure water is neither acidic nor basic. Water changes its pH when substances are dissolved in it. Rain has a naturally acidic pH of about 5.6 because it contains natural derived carbon dioxide and sulfur dioxide.
> Water conducts heat more easily than any liquid except mercury. This fact causes large bodies of liquid water like lakes and oceans to have essentially a uniform vertical temperature profile.
> Water molecules exist in liquid form over an important range of temperature from 0 - 100° Celsius. This range allows water molecules to exist as a liquid in most places on our planet.
