No. The mass of an object doesn't change (Law of Conservation of Mass), therefore its weight won't change either (weight = mass x gravity).

When will an object change its state of motion?
An object changes its state of motion when it accelerates or decelerates, usually caused by a force.
What does the change in state involve?
A change of state is a change in the object from a solid to a liquid. Other changes of state are a solid to a gas or from a liquid to a solid.
Does a substance change mass if it changes physically?
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
Does pressure affect changes of state?
yes, if you apply pressure to an object it will change the state, by changing the shape of it
State the ways velocity can change?
the velocity of an object changes when it speeds up or slows down.
What change of state and what energy changes occur when water freezes?
the state change is from liquid to solid and the energy change is cold energy to heat energy
Is sublimation of mothballs physical or chemical change?
Physical, since it's just changing the state of matter
Are state changes physical or chemical changes?
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
What is the difference between phyical and chemical changes?
A physical change only changes the appearance of an object, it's chemical makeup is still the same. Melting ice doesn't change it to a different object, just a different state. Like if you rip a piece of paper, it's still a piece of paper. But a chemical change changes the makeup of the object. Burning is a chemical change. Once it burns it is no longer paper.
Why are changes of state chemical changes?
They aren't; a change of state is a physical change
What is inertia mean?
is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction.
What are physical and chemical changes and how are they the same and how are they different?
Physical changes are changes in something that affects the objects physical characteristics. Meaning things like the color, shape, amount. Example: cutting a piece of paper, painting a wall, etc. Chemical changes change what the object is made of. It can change everything, including the state the object(or liquid) is in.
