What else can I help you with?
What happens when a substance changes from solid to liquid?
The molecules/atoms move far apart. As the separation between paricles increase, the state is changed. The temperature does not rise because the heat is used to overcome inter-molecular forces.
When the temperature of matter decreases, the particles do what?
The particles move more rapidly
What is space between particles of soil is called?
Normally free floating particles and gases such as oxygen, nitrogen etc.
What is it called when water move soil particles?
The process of water moving soil particles is called erosion. Erosion occurs when water carries away soil particles, resulting in the loss of fertile land and potential damage to ecosystems. Measures such as planting vegetation and constructing barriers can help prevent erosion.
A substance whose shape can easily change is a?
Spongebob
What is a substance that has a definite shape and volume and whose particles are packed tightly together in fixed positions and cannot move?
a solid.
What is the average speed of the particles of a substance?
The average speed of particles in a substance is determined by the temperature of the substance. At higher temperatures, particles move faster, while at lower temperatures, particles move slower. This average speed is related to the kinetic energy of the particles.
When the particles of a substance move around faster what do they cause the substance to do?
stge
If the particles of matter that make up a substance are relatively far apart and can move freely the substance?
If the particles of matter that make up a substance are relatively far apart and can move freely, the substance is likely in a gaseous state. Gas particles have a lot of space between them and move independently of one another.
What substance is solids?
It is a substance that has a lot of particles that are packed together. The particles can not move becase the solid paticles are to strong.
What is meaning of fluid?
Having particles which easily move and change their relative position without a separation of the mass, and which easily yield to pressure; capable of flowing; liquid or gaseous., A fluid substance; a body whose particles move easily among themselves.
When the particles of a substance move about faster they spread out causing the substance to what?
Change states
When the particles of a substance move faster they spread out causing the substance to what?
Change states
A substance that keeps its shape because its particles can't flow freely is a or an?
A substance that keeps its definite shape because it cant move freely is called a solid.
What are motion of particles that finish melting called?
The motion of particles that occurs once a substance has completely melted is called fluid motion. In the fluid state, the particles move freely and do not have a fixed shape or volume.
Do the particles in solid ice move slower than the particles in liquid?
Yes. The colder the substance become, the slower the particles move. Actually in pure ice the particles do not move at all.
Does temperature measure how fast the particles of a substance are moving around?
Yes, temperature is a measure of the average kinetic energy of particles in a substance. When temperature increases, the particles move faster, and when it decreases, they move slower.
