Yes, it does.
Freezing is the term for the phase change from the liquid phase into the solid phase.
Any change of phase occurs with a change in heat energy.The heat energy exchanges present during a change in phase are changes in potential energy.
In none of the changes of phase is heat input used to speed up the molecules, nor is heat output ever occurring as a result of the molecules slowing down.
The average speed of molecules is the same before and after a phase change, so the average kinetic energy (temperature) is the same.
At melting point of a substance the supplied heat is utilized to change the state so temperature remains constant till all the material is converted into liquid, this is known asLatent heat of fusion.
Temperature and the amount of gas (moles) must be kept constant for Boyle's law to hold true. This means the pressure and volume of a gas are inversely proportional provided the temperature and amount of gas remain constant.
"Constant pressure" means the pressure must not change.
The reason that the temperature in an ice bath remains constant for several minutes after placing a beaker in a warm water bath, is that it takes water longer to heat. The cold water will not heat up right away because the energy hasn't transferred.
The volume of the gas must remain constant for pressure and temperature to be directly proportional, according to Boyle's Law. This means that as the pressure of a gas increases, its temperature will also increase proportionally, as long as the volume is held constant.
1. A more correct name is Boyle-Mariotte law. 2. Only the temperature must remain constant.
The temperature remain constant.
No. During a phase change, a substance will remain at a constant temperature until the change is complete. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.

Yes, ice has a definite volume because it is a solid state of water molecules that are fixed in position. The volume of ice will remain constant as long as there are no changes in temperature or pressure.
The temperature and speed remain constant.

The variable that Boyle's law holds constant is the temperature. Boyle's law states that the pressure of a gas is inversely proportional to its volume, as long as the temperature remains constant.
