Can we consider water a fluid? Give suitable explanation also.
(b)Which one out of water and wood can be compressed easily and why?
(c)Give an example of diffusion of liquid in liquid.
Answers
Answer:
water is considered as fluid bcoz :
bcoz they can flow easily and do not have fixed shape
1)water can be compressed easily than the wood because the molecules of water are more lightly packed than that of wood
2)milk in water or alcohol in water
Answer:
a) Water at room temperature is a liquid.
Water at room temperature is liquid due to the presence of hydrogen bond. These bonds hold water molecules together for small fractions of a second. Water molecules move continuously. In gaseous matter there is random movement. Because of the hydrogen bonds, the water molecules come together they stick to one another for a small, but significant amount of time. This reduces the motion of them and holds them closer to one another. This property makes the water liquid at room temperature.
Characteristics of liquid
Liquid has the following characteristics:
At room temperature, water has no shape but has a fixed volume i.e., it occupies the shape of the container in which it is kept.
At room temperature, water flows easily.
b) An iron almirah is a solid at room temperature.
An iron almirah is a solid at room temperature (25°C) because:
It has a definite and rigid shape and
Fixed volume like a solid at room temperature.
On applying external force the shape does not get deformed
