What happens to particles when heat energy is absorbed during melting?
After heat energy is absorbed during melting the atoms and molecules start moving away from each other as the force of attraction becomes weak. At one point the atoms or molecules move so further away that the solid turns into a liquid.
Why do different substances require different amount of heat energy during melting?
due to different melting point...
During which change is energy absorbed?
the melting of ice
What happens to the particles of matter during a phase change?
The particles change mean speed and concentration.
How do particles move during lower temperature?
Particles will move more slowly at lower temperatures.
During which processes do particles of matter absorb energy?
condensation and melting
Heating a solid makes it melt terms of particles?
The particles are moving away from one another during melting.
What statement describes negative population growth?
More people die than are born during a given period is a statement that describes negative population growth. The statement describes negative population in Western Europe.
What statement best describes the population of the US in the 1900s?
the popularity grew steadily during the 1990s.
When a solid melts do its particles gain or lose heat energy?
A material must gain energy both before and during melting.
Which statement best explains why turbigenic sediments are found in graded beds?
During deposition, larger particles usually settle to the bottom faster than smaller particles do.
How does what happens to the particles in a substance during melting differ from what happens during freezing?
When something is heated the particles inside it begin to move faster and faster and that causes the heat, when something is frozen the opposite occurs the particles inside it move slower and slower and probably stop moving all together
Which statement describes the situation in Russia during the 200years when the Mongals ruled?
Russia was isolated and paid tribute to the Khans.
What is a good Statement best describes the function of the reconstruction finance corporation?
it authorized loans during the Great depression
Which statement best describes the national economy during the gilded age?
The price of economic goods fell during the time period from 1865 to 1896
What happens to the particles of a crystalline solid as it is heated at its melting point?
The particles start to move randomly as the process of the liquid starts to form. So during the transformation the bond between the particles start to move. The particles begin to move randomly, and then the crystalline forms a liquid. The faster the particles move the more it transforms into a liquid.
What statement best describes the political views of the colonist during the revolutionary war?
The colonists were evenly divided in their political views
