How a diver is able to cut through water in a swimming pool which property of matter does this observation show?
forces of attraction
Which property of matter does this observation show? Answer: The particles of water are held together by forces of attraction. It is the reason that the diver is able to cut through water in a swimming pool.
Can we cut through water?
– The forces between the molecules of liquid are not as much as solid. However, the forces are more than the forces acting between the molecules of the gases. – Thus, we can conclude that the spaces between the molecules are there in water and that makes the diver cut the surface of the water.
What is the characteristics of particles of matter?
Characteristics of particles of matter All matter is composed of very small particles which can exist independently. Particles of matter have spaces between them. Particles of matter are continuously moving. Particles of matter attract each other.
What are the two physical nature of matter?
Modern day scientists classify matter in two ways: on the basis of its physical properties and on the basis of its chemical properties. On the basis of physical properties, matter is classified as solids, liquids and gases. On the basis of chemical properties, matter is classified as elements, compounds and mixtures.
Why do swimmers move in water?
By moving his or her arms through the water the swimmer creates a thrust force that propels the swimmer forward. For a swimmer moving at constant speed through the water the thrust force is equal to the drag force. The faster an object moves through a fluid the greater the drag force.
Why is it possible for us to cut through water easily and not through ice?
A diver will pass through water if there is the availability of space between the particles and the forces of attraction between the liquid particles are not very strong. The diver will not cut through solid ice because of fewer spaces between the solid particles and strong forces of attraction.
What are the two main characteristics of matter?
Matter and Its Characteristics It has mass and occupies space. Mass is a physical quantity which expresses the amount of stuff in an object. The space inside the container that is occupied by matter is its volume.
What are the 12 particles of matter?
The 12 elementary particles of matter are six quarks (up, charm, top, Down, Strange, Bottom) 3 electrons (electron, muon, tau) and three neutrinos (e, muon, tau). Four of these elementary particles would suffice in principle to build the world around us: the up and down quarks, the electron and the electron neutrino.
What are the two physical nature of matter Class 9?
Physical nature of matter: Based on the physical nature of matter, there are three States of Matter: Solid: Molecules are tightly packed. They are often hard and rigid. Liquid: Molecules are loosely packed as compared to that of a solid.
What is the chemical nature of matter?
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
Were you able to cut the surface of water what could be the reason behind the surface of water remaining together?
Explanation: As the particles of water have some intermolecular space between them and also some force of attraction.By overcoming the force of attraction we are able to cut the stream and it is responsible for surface of water remaining together.
What are the 3 characteristics of matter Class 9?
The characteristics of particles of matter are:
- All matter is composed of very small particles which can exist independently.
- Particles of matter have spaces between them.
- Particles of matter are continuously moving.
- Particles of matter attract each other.
What are three characteristics of all matter?
Key Points
- Matter can exist in one of three main states: solid, liquid, or gas.
- Solid matter is composed of tightly packed particles.
- Liquid matter is made of more loosely packed particles.
- Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.
What are the 31 fundamental particles?
31 seems a lot of elementary particles, but most of what we think of as matter consists of just 3 of them: the up quark, the down quark and the electron (protons and neutrons are both made of up and down quarks; atoms are made of protons, neutrons and electrons; most of what we think of as matter is made of atoms).
How many quarks exist?
12 different quarks
There are 12 different quarks in total. The number rises to 36 if you take the color charge into account.What is nature of matter Class 9?
