What kind of property is melting point and freezing point of water?
The melting point and freezing point of water are physical properties.
What kind of changes are melting and boiling?
Melting is a phase change where solid becomes a liquid. The latent heat of fusion must be supplied to produce phase change from solid to liquid. About 144 Btu must be supplied to change 1.000 pound of ice at 32 degrees F to 1.000 pound of liquid water at 32 degrees F. Boiling is a phase change where a liquid becomes a vapor. The latent heat of vaporization must be supplied to change a boiling liquid to a vapor. For water boiling at 14.7 psia ,970.3 Btu of heat must be supplied to change 1.000 pound of boiling liquid water to vapor.
Physical properties are altered but the substance remains the same kind of matter?
Melting ice to get water, or boiling water to get steam, doesn't change the identity of H2O.
What kind of sprinklers do not need melting to set it off?
Frangible bulb do not need melting to set off the water
A material that contain only one kind of atom?
An element. eg soduim: Na You can get diatomic and polyatomic ions/molecules like O2 and S8 which are normally gaseous. These contain only one kind of atom.
What kind of changes are melting and freezing?
Melting, freezing, boiling, evaporation are physical change
What kind of change is melting and freezing?
physical change
What kind of property is melting point and freezing point of water?
The melting point and freezing point of water are physical properties.
What kind of change occures when ice become liquid water?
physical change because it is melting and it would be the same mass as it waas as a chunk of ice

What kind of change occurs with freezing water?
A phase change.
Melting a sugar cube is what kind of change?
physical change
What kind of salt to use on sidewalks for snow?
Salt works by lowering the melting or freezing point of water. The effect is termed 'freezing point depression'.
What kind of process is the boiling of water?
Boiling is a physical process, a change of phase.
Physical properties are altered but the substance remains the same kind of matter?
Melting ice to get water, or boiling water to get steam, doesn't change the identity of H2O.
What kind of change is the freezing of a substance?
Liquid to solid.
