What are the examples of Contraction in solid liquid and gas?
Solid: contraction occurs when a solid cools down and its particles move closer together, causing the object to shrink in size. Liquid: contraction takes place when a liquid cools and its particles lose kinetic energy, leading to a decrease in volume. Gas: contraction occurs when a gas is cooled and its particles move closer together, resulting in a decrease in volume.
Describe what happens to particles on the surface of a liquid as it evaporates?
As the liquid evaporates, particles on the surface gain enough energy from the surroundings to break free from the intermolecular forces holding them in the liquid phase. These particles then escape into the surrounding atmosphere, causing the liquid to gradually decrease in volume.
Why can you not compress a liquid?
The particles in a liquid are close together. In a solid the particles are tightly packed together so you cannot compress them at all. The particles in a gas are far apart, so when they are compressed the volume of the gas reduces. The bonds in a liquid are not as close as those in a solid but they are still too close for compression.
What happens to particles when condesing?
When particles condense, they come together to form a denser phase, such as a liquid from a gas or a solid from a gas. This process releases heat energy and allows the particles to move closer together, resulting in a decrease in volume.
Do particles increase or decrease at cold temperatures in a balloon?
Particles in a balloon decrease at cold temperatures because the gas inside the balloon contracts as it cools down, resulting in a decrease in volume and therefore a decrease in the number of gas particles.
What happens to the particles of a liquid as the liquid freezes?
As a liquid freezes, its particles slow down and move closer together, forming a solid crystal lattice structure. This results in a decrease in the random motion of the particles and a decrease in the volume of the substance as it transitions from a liquid to a solid state.
What happens when the vacant spaces between the particles of a liquid decreases how can you do this?
When the vacant spaces between particles of a liquid decrease, the liquid becomes more dense and its volume decreases. This can be achieved by applying pressure to the liquid or by cooling it, which causes the particles to come closer together and occupy less space.
When a substance changes from a solid to a liquid its density normally decreases. What is happening to the substance's mass and volume to cause this decrease in density?
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
Do a gas' particles decrease when it turns to liquid?
Yes, when a gas turns into a liquid, the particles are closer together and have less kinetic energy compared to when they were in the gas phase. This results in a decrease in the volume occupied by the particles but an increase in the density of the substance.
What are the examples of Contraction in solid liquid and gas?
Solid: contraction occurs when a solid cools down and its particles move closer together, causing the object to shrink in size. Liquid: contraction takes place when a liquid cools and its particles lose kinetic energy, leading to a decrease in volume. Gas: contraction occurs when a gas is cooled and its particles move closer together, resulting in a decrease in volume.
What is the result increasing the volume of a gas?
A decrease of pressure.
What would cause the pressure of a gas to increase?
An increase in temperature or a decrease in volume would call the pressure to increase. Apex- increasing the number of gas particles
Describe what happens to particles on the surface of a liquid as it evaporates?
As the liquid evaporates, particles on the surface gain enough energy from the surroundings to break free from the intermolecular forces holding them in the liquid phase. These particles then escape into the surrounding atmosphere, causing the liquid to gradually decrease in volume.
How does the movement of particles in a liquid help to explain the shape and volume in a liquid?
Because its particles are free to move, a liquid has no definite shape. However, it does have a definite volume.
Why can you not compress a liquid?
The particles in a liquid are close together. In a solid the particles are tightly packed together so you cannot compress them at all. The particles in a gas are far apart, so when they are compressed the volume of the gas reduces. The bonds in a liquid are not as close as those in a solid but they are still too close for compression.
What happens to volume of liquid during compression?
The volume of a liquid responds poorly to compression, but might decrease slightly.
Why does water get a lower density when frozen?
density is mass/volume that is the total mass per 1cm3 of the liquid in question. as water becomes colder, its particles loose energy and move closer together, increasing the number of particles per 1cm3 and therefore increasing the amount of mass in that 1cm3
