Answer 1

Answer:

1-

2- solid have fixed shape because their constuant particle are tightely packed whereas liquid and gases particle are loosely packed.

3- because it make our food faster when the pressure of inside the coocker is equal to atmospheric pressure .

Answer 2

Hey User,

Here is Your answer

• The Water Vapour present in air Coming in contact with the glass containing Ice looses the energy and Get Converted into liquid state which we see as tiny Droplets.

• Solids Have high Intermolecualar Force of attraction Which Keeps the particles tightly packed with each other while liquid and gases have low force of attraction.

• At higher altitudes, the atmospheric pressure is low and the water boils very fast and evaporates at faster rate therefore the pressure is required to increase the cooking process and this is done by using pressure cooker which increases the pressure inside the container and cooks food faster

• The fluid are those substance which flow for ex-Liquid and gases.

• Water Does bot have definite shape,Water have low Force of attraction.

• cotton has a porous structure, the air gets trapped between the pores making overall density of the cotton less then the water hence the cotton floats on the water. when the water replaces the air the pores, the density increases and the cotton sinks

• Why are solids generally denser than liquids and gases. Solids are more denser as the intermolecular force of attraction between the particles are more and they are packed tightly. So the density is more for solids

• Factors are-
• Temperature
• Surface area
• Wind
• Humidity
• Nature of liquid i.e Volatile liquid evaporate faster.

• Due to this propert gas can be transported everywhere by keepimg them in small comtainer.It is used as CNG which is very useful.

• On a sunny day,The temperature is high which is major factor of evaporation.Sprinkled water evaporates faster which cause Cooling.

• We perspire a lot in Summer because it is the factor evaporation due to this only we feel Cool when we come directly Front of the fan

• The air trapped in Balloon get evaporated when there is high temperature Whuch leads to Brusting.

• Applying pressure-->Gas-Liquid-Solid Because the particles started coming close with each other

• Applying temperature---Solid----Liquid--->Gas Because particles get stated geeting far away fron each other.
