Question

Prove by an activity that the particles of matter have space between them explain with the diagram

Answer 1

Activity: 

When we dissolve salt/sugar in water, the particles of salt/sugar get into the spaces between particles of water.

Equipment’s Required: - 

• Beaker
• BeakerWater
• BeakerWaterSalt/ Sugar,
• BeakerWaterSalt/ Sugar, a glass rod.

Working:

• Take a 100 mL beaker.
• Take a 100 mL beaker.Fill half the beaker with water and mark the level of water.
• Take a 100 mL beaker.Fill half the beaker with water and mark the level of water.Dissolve some salt/ sugar with the help of a glass rod.
• Take a 100 mL beaker.Fill half the beaker with water and mark the level of water.Dissolve some salt/ sugar with the help of a glass rod.Notice the water level.

Observations:

• When sugar/salt is dissolved in water, the particles of sugar disappear in water. This happens because particles of sugar/salt get adjusted in the spaces between the particles of water.

• Additionally, you will notice that there is no rise of water level takes place when one or two teaspoons of sugar is added in a glass of water, this is because sugar particles get adjusted in the space between the particles of water and no rise in the water level comes in result.

• This activity shows us that Matters are made of small particles. And there is space between these particles.
