What occurs when particles in a substance move faster and occupy a larger space without changing to another state of matter?
Thermal expansion
Substances expand when heated because the molecules?
According to the particle theory, particles move faster and further apart when exposed to higher temperatures. When a substance is heated, its particles acquire thermal energy. These energetic particles--which are constantly vibrating, even in solid form--become very excited, and move around much more, therefore requiring more space. The substance begins to increase in volume, creating larger spaces in between its molecules to accommodate the high-energy movement. This can also cause a change in state. Particles of substance in a solid state: vibrating slightly, densely packed together, little space between molecules. Compare to, Particles of substance in a gaseous state: vibrating excitedly, larger spaces in between molecules, easily compressible (due to empty spaces) If you were to cool a substance in gaseous form, the particles would begin to lose their thermal energy, and eventually change into a liquid state.
What is the difference between a small dam and a large one?
The large dam is larger...pretty self explanatory. Also the larger dam will be heavier, take up more space, stop more water, and lots more.
Why do larger disturbed areas take longer to recover?
because the larger it is the more space there is that has to be recovered and the deeper the damage can go.
What word is used to describe the amount of space matter takes up?
The other way of saying this is "what is the volume occupied by the substance".
What is the movement of a substance from a small space to a larger space?
The movement of a substance from a small space to a larger space is known as diffusion. Diffusion occurs due to the random movement of particles from an area of high concentration to an area of low concentration until equilibrium is reached.
Why does mercuri expand when heated?
When thermal energy is added to a substance, the molecular movement increases. Because they are moving around, they need more space, which is provided by occupying a larger volume.
Does mercury expand when heated?
When thermal energy is added to a substance, the molecular movement increases. Because they are moving around, they need more space, which is provided by occupying a larger volume.
Where does asteroid come from?
Asteroids are small fractions of much larger stars, planets, and rocks in space.
What occurs when particles in a substance move faster and occupy a larger space without changing to another state of matter?
Thermal expansion
If larger turtle is attacking smaller one how do you stop it?
Give them extras space and you can put small hiding place for the small turtle
How does sand and gravel size influence hydraullic conductivity?
The smaller the grain, the less pore space there is to allow fluid movement. The larger the particle grains, the greater the movement due to the overall increase in pore space between particles.
Why does heat cause expansion?
Heat causes expansion because it increases the speed at which particles vibrate within a substance, creating more space between them. This increased movement and spacing of particles lead to an overall expansion of the substance.
A concentration gradient ceases to exist when?
A concentration gradient ceases to exist when there is an equal distribution of a substance across a space or membrane. This equal distribution results in no net movement of the substance from one area to another, causing the concentration gradient to reach equilibrium.
What is the definition for the word diffusion?
Diffusion refers to the process of a substance spreading out to fill the available space. It occurs due to the random movement of particles.
When a substance is heated do the particles get larger?
When a substance is heated, the particles do not get larger but they vibrate faster and spread out more, causing the substance to expand. This expansion is due to the increase in kinetic energy of the particles, not their actual size.
How is Earth a small part of a larger outer space sysytem?
We are just one part of a larger system, and are reliant on that system for our continued existence. We harm it at our peril.
