What is the physical state of water at100C?a)Liquidb)Solidc)gasd)All of theseCorrect answer is 'B'. Can you explain this answer?

Question

Answer

The answer is a .

The physical state of water at its boiling point temperature of 100 degree Celsius will be both liquid state as well as gaseous state. This is because at its boiling point of 100 degree celsius the liquid state of water starts changing into its Gaseous state (steam).

Answer

Correct answer is a

Answer

The correct ans is a not b

Answer

From 0' C upto 100' C , water is in liquid state ....so at 10' C water is at liquid state so the correct answer is B.

Answer

I think the correct answer is A...As after 4•c the ice or solid form of ice used to convert to water....it remains liquid upto hundred degree Celsius...

Answer

Correct answer is a not b

Answer

IT'S  option A- liquid..

Answer

Option B is correct

Answer

As we lower the temperature of liquid water, it becomes denser until you reach 4 degrees Celsius (centigrade). It is still a liquid.Hence the reason

Answer

Water freezes

Answer

B

Answer

Physical State of Water at 100°C

Introduction:
Water is a compound made up of two hydrogen atoms and one oxygen atom. It is essential for life on Earth and exists naturally in three different physical states: solid, liquid, and gas. The physical state of water depends on its temperature and pressure.

Liquid State:
At normal room temperature and pressure (around 20-25°C and 1 atmosphere), water exists in its liquid state. It flows freely and takes the shape of its container. This is the most common state of water that we encounter in our daily lives.

Boiling Point of Water:
The boiling point of a substance is the temperature at which it changes from a liquid to a gas at a given pressure. For water, its boiling point is 100°C at atmospheric pressure (1 atmosphere or 101.3 kPa). When the temperature reaches or exceeds 100°C, water undergoes a phase transition from its liquid state to its gaseous state, which is known as vaporization or boiling.

Water at 100°C:
When water is heated to 100°C, it reaches its boiling point. At this temperature, the water molecules gain enough energy to overcome the attractive forces between them and transition into a gaseous state. The water molecules move more rapidly and become less organized as they transform into water vapor.

Phase Transition:
During the phase transition from liquid to gas, the temperature remains constant at 100°C until all the liquid water has vaporized. This is because the energy supplied to the system is primarily used to break the intermolecular bonds and convert the liquid water into water vapor, rather than increasing the temperature.

Conclusion:
In summary, at 100°C, water exists in its liquid state. It is important to note that this is true only at standard atmospheric pressure. If the pressure is altered, the boiling point of water can change. For example, at higher elevations where the atmospheric pressure is lower, the boiling point of water decreases. However, under normal conditions, water boils at 100°C and transitions into a gas.
