What happens to the distance between particles of a substance as it changes from a liquid to a gas?
The distance increases, as the particles become more energetic and the substance loses its definite volume, as the particles bounce around, due to heat/increased energy.
What effect does the speed of molecules have of matter?
The speed of the particles in a substance changes when the temperature changes. Heating the substance causes the particles to speed up, while cooling causes the particles to slow down.
What are the following changes of state and explain how particles behave in each state?
The temperature at which a liquid becomes a solid is freezing point and when a solid is turned into a gas it is called sublimation. For a liquid to freeze the attractions between the particles must overcome their motion.So,Freezing; a liquid to a solid.Sublimation; when a solid becomes a gas.About Particles; they must overcome their motion
Explain why the temperature of Wax remains constant during solidification?
it's because it releases the latent heat of fusion. Latent heat means energy is given out when a substance changes from liquid to solid without a change in temperature. and the transfer of energy doesnt change the KE of the particles, so the temperature remains unchanged. lanten heat gives rise to the change in PE of the particles during the change of state only
How do changes in temperature and energy influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
What happens to the temperatures of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
Is the speed of the particles in a substance changes when the temperature changes?
Yes, in fact, particle movement is what heat is.
What is the relationship between the amount of space between particles and the state of the matter?
As the space changes between the particles, so does the state of matter.
How do changes in temperature cause rock fragmentation?
Rocks expand and contract depending on the temperature. After repeated exposure to temperature cycles, the surface of a rock may experience weakness in the bonds between crystals or particles, causing a delamination of the outer layer.
Explain how the motion of particles in an object changes when its temperature increases?
When temperature increases the particles of an object gain more heat energy, therefore move faster colliding with each other more.
When you compress matter do the particles change size?
no, the space between them changes.
Has thermal energy been transfered into or out of a substance if the average kinetic energy changes?
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
What best describes the relationship between heat and temperature heat and temperature are the same thing heat changes temperature heat is a measure of temperature or temperature measures?
The flow of heat in and out of an object changes its temperature.
What is the changes between soild and gas states - during ---- the surface particles of solid gain enough energy to become a gas?
This process is known as sublimation. A typical example of this is dry ice at room temperature.
What happens to particles of matter when a liquid changes to a gas?
well, in a gas, there is pressure and temperature. the particles move farther apartThe move faster and get further apart from each other.
What happens to the temperature when bonds are broken?
If you mean the bonds as in the bonds between particles at different states of matter. Then the temperature actually effect whether the bonds break or not, if the bonds in matter break the state of matter changes to a gas, whose particles are free moving and are completely unattached. Different liquids change to gas at different temperatures. Hope this helped :)
How does adding energy to matter by heating it affect the energy of its particles?
Adding heat will do one of the following, or both: * The temperature of the substance increases. The individual particles move faster; their kinetic energy increases. * The substance changes its state (for example, when ice melts, it changes from solid to liquid). The potential energy of the particles increases.
