What else can I help you with?
What happens to the mass when a physical change happens?
During a physical change, such as melting or boiling, the mass remains constant. The atoms and molecules rearrange themselves, but none are added or lost, so the total mass remains unchanged.
If you move an object from the base of a mountain to the top of the mountain what remains unchanged?
The mass of the object remains unchanged, as it depends only on the amount of matter in the object.
Which type of radioavtive decay does the mass number remain unchanged?
In gamma decay, the mass number remains unchanged as there is no emission of particles, only high-energy gamma rays are emitted. This process does not affect the nucleus composition, unlike alpha and beta decays which result in a change in the mass number.
If an object is melted does the mass stay the same?
Yes, the mass of an object remains the same when it is melted, as mass is a conserved quantity in physical processes like melting. The atoms or molecules that make up the object may change their arrangement or state, but the total mass remains constant.
What happens to density when either mass or volume increases and the other remains unchanged?
If mass increases while volume remains constant, density will also increase. Conversely, if volume increases while mass stays constant, density will decrease. Density is calculated by dividing mass by volume, so any change in either variable will affect the density.

When a junk car is crashed into a compact cube does it changed the mass volume and the weight?
The mass and weight are unchanged. The volume is reduced.
When an ice cube melts does it have the same mass as before?
Yes, the mass of the melted ice cube remains the same as the original ice cube. When ice melts, it undergoes a phase change from a solid to a liquid, but the total amount of matter remains constant.
Is your weight the same on earth as it is on the moon?
No. You are lighter on the moon than on earth, though your mass remains unchanged.
What happens to the mass when a gas or liquid is heated?
The amount of mass does not change. The energy contained by the fixed mass increases.
If you are in the moon will your mass be lighter and your weight will still be the same?
No, just the reverse. Your mass remains unchanged, but your weight will be about 1/6 earth-normal.
What happens to an ice cubes particles when the ice cube is melting does the weight remains the same?
As the ice cube is solid , the particles are tightly packed together but as it melts it changes to a liquid so the particles change so that they are like particles in a liquid. the mass is conserved ( stays the same)
Which property of water remains unchanged when it recycles in the atmosphere?
a. mass b. density c. physical state d. molecular arrangement
When a gas or liquid is heated then its mass is?
The mass remain unchanged.
Does candle loss mass when melting down?
No, a candle does not lose mass when melting down. The wax that is melted simply changes from a solid to a liquid state, but the total mass of the candle remains the same.
When an atom undergoes oxidation what happens to the number of neutrons?
Oxidation is a chemial reaction; the atom and the number of neutrons remains unchanged.
