Water is different from other substances

Chemistry

Gnoma [55]3 years ago

Answer: Option (b) is the correct answer.

Explanation:

It is known that density is the amount of mass divided by volume.

When water is present in solid state that is, in the form of ice then its molecules arrange themselves in a rigid tetrahedral structure.

Due to this there will cage like spaces between the molecules of ice during the bonding. As a result, they occupy more volume and it is known that density is inversely proportional to volume.

Hence, ice has low density as compared to liquid state of water.

When water is present in liquid state, then its molecules are closer to each other and they are able to slide past each other. Hence, space between them is less therefore, lesser will be its volume.

As a result, liquid state of water will have more density.

Thus, we can conclude that water is different from other substances  because it is less dense as a solid than liquid.

It's more dense as a liquid than as a solid. That's why ice can float in water. The answer is B.

why do solids keep their shape and volume why do liquids keep only volume and why do gases not keep either shape or volume
kodGreya [7K]
Solids always have definite shape and definite volume because their particles are packed together. Liquids have a definite volume but not definite shape, because their particles still kinda tight but able to move around, and gases don’t have a definite shape nor volume, because their particles are crazy and go everywhere

What is the frequency of radiation whose wavelength is 2.25 X 10^-5cm?
Semenov [28]

Answer:

1.25 x 10^15Hz

Explanation:

c = frequency x wavelength

c is the speed of light, which is equal to 3.00 x 10^8 m / s

frequency = c /wavelength

= (3.00 x 10^8m /s) / (2.40 x 10^-5 cm x 1 m /100cm)

= (3.00 x 10^8 m/s) / 2.40 x 10^-7m

= 1.25 x 10^15/s 1 / s = 1Hz

So, the Frequency = 1.25 x 10^15Hz

I hope this helped :)
