What change is melting consider because energy is gained by the substance as it changes states?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Changing phases is also a physical change.
The sum of the kinetic and potential energy of the molecules of a substance?
thermal
Which may be true for a substance that absorbs energy?
The energy decreases the molecular motion and the kinetic energy of the substance.
What is an average kinetic energy of the particle of a substance?
The term kinetic energy means the energy of motion. It is calculated by multiplying one half of the mass of the moving object by the square of the velocity.
Is it true that the temperature of a substance changes from liquid to gas?
No. the temperature doesn't change, the substance does. yes the temperature of a substance alway changes from liquid to gas because it needs more kinetic energy for a liquid to go to the gas state breaking the intermolecular forces
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
The temperature at which the particles of a substance have more kinetic energy to transform is?
The melting or the boiling point.
The kinetic energy of a substance is the what kinetic energy of its particles?
The kinetic energy of a substance is the average kinetic energy of its particles.
What is the kinetic energy of a substance and the kinetic energy of its particles?
The kinetic energy of a substance is the average kinetic energy of its particles.
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
How is the kinetic energy of the particles that make up a substance different after it changes?
If you mean by heating it... When you heat a substance, the thermal energy of its particles increases. This means that the particles will move around faster as they have a higher kinetic energy.
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 change is melting consider because energy is gained by the substance as it changes states?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Changing phases is also a physical change.
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.
Why the inter-particle space increases on heating a solid at its melting point?
when we heat a substance its kinetic energy increases and due to this kinetic energy the force of attraction decreases and can no longer hold the particles together.
Does the temperature change if the average kinetic energy of a substance changes?
When Ave KE increases temperature increases.
What happens to the kinetic energy of the particles of a substance as the changes from a liquid to a gas?
in my opinion, I don't really know
