What happens to the kinetic energy of the particles in the substance during process condensation?
The average kinetic energy of the particles falls.
Heating a solid makes it melt terms of particles?
The particles are moving away from one another during melting.
What happens when the temperature stays the same in a melting curve?
During melting the temperature remain constant if it was achieved the melting point.
A substance has a melting point of 14c and a boiling point of 78c in what state is the substance at 78c?
The substance would be in a liquid and gas state, this would be due to vaporization that is happening during boiling.
What happens to the original substance during a chemical reaction?
The original substances are transformed during a chemical reaction a new substance (compound) is obtained.
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
What happens to matter and the particles of an object during physical change?
The particles are affecting the form of a chemical substance and not turning into a new substance.
What happens to the kinetic energy of the particles in the substance during process condensation?
The average kinetic energy of the particles falls.
How does what happens to the particles in a substance during melting differ from what happens in freezing?
Its the degree of attachment between the molecules of the substance: frozen (solid) the arrangement is fixed. melted (liquid) the arrangement is loose enough to be modified by gravity. evaporated: (gas) the attachment becomes insignificant.
What happens to substance during changed between liquid and gas?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
What happens to substance during changes between gas to liquid?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
During which processes do particles of matter absorb energy?
condensation and melting
Is energy released during melting?
No. When a substance melts it absorbs energy.
Heating a solid makes it melt terms of particles?
The particles are moving away from one another during melting.
What changes during melting?
The substance absorbs the heat of fusion. The temperature does not go up, but the form of the substance changes.
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 happens when the temperature stays the same in a melting curve?
During melting the temperature remain constant if it was achieved the melting point.
