How does the motion and arrangement of particles in a substance change as the substance freezes?
Freezing changes a liquid to a solid. Describe how the motion and arrangement of particles in a substance change as the substance freezes. As a substance freezes, its particles lose some of their freedom of motion and become more orderly.
How does the motion of the particles in a substance relate to what state the substance is in?
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
What causes the change in the arrangement of the particles?
The kinetic theory of matter can be used to explain how solids, liquids and gases are interchangeable as a result of increase or decrease in heat energy. When an object is heated the motion of the particles increases as the particles become more energetic.
What happens to particles when a substance changes state?
The particles in a substance stay the same when it changes state – only their closeness, arrangement or motion change. This means that the mass of the substance stays the same. For example, 10 g of water boils to form 10 g of steam, or freezes to form 10 g of ice. This is called conservation of mass .
Does the size of the particles change as the substance changes state?
Particles stay the same size and shape during state changes. Particles move around and are not static. Freezing means ‘liquid changing to solid’ and does not rely on cold temperatures.
What is a word for a sudden change?
other words for sudden change break with the past. conversion. marked transformation. metamorphosis. quantum leap.
