Solved Questions For You:

Question 1. A diver is able to cut through water in a swimming pool. Which property of matter does this observation show?

Answer: The diver is able to cut through water in a swimming pool. This observation shows that the matter has spaces between them so that the particles can move from one place to another to accommodate the body of the diver.

Question 2. Give reasons for the following observation:

The smell of hot sizzling food several metres away, but to get the smell from cold food you have to go close.

Answer: Particles of hot food have more kinetic energy than the particles of cold food. Due to more energy, they can travel easily or diffuse through the air very fast and can be reached several meters away.

But the particles of cold food are low in energy and the tendency to travel is very less so to get the smell from cold food we need to go close to the food.

Question 3. Which of the following is(are) matter?

Chair, air, love, smell, hate, almonds, thought, cold, cold-drink, the smell of perfume.

Answer: The matter is something that has weight and occupies space. So according to the definition,

matter: Chair, air, almonds, cold-drink.

Question 4. What are the characteristics of the particles of matter?

Answer: The characteristics of the particles of matter are:
  1. The particles of matter have spaces between them
  2. The particles of matter are continuously moving
  3. The particles of matter attract each other
  4. The particles of matter are very, very small.
