The melting point and boiling point remain constant when the physical state is changed.
The speed of an object in circular motion remains constant while the direction of the velocity changes continuously.
To say that a physical quantity is quantized means that it can only take on discrete values or multiples of a fundamental unit. Conservation of a physical quantity means that the total amount of that quantity remains constant over time in a closed system, even if it may change forms.
A conserved physical quantity is a property of a system that remains constant over time for an isolated system under certain conditions. This means that the total amount of that quantity within the system does not change, even as other processes take place. Examples include energy, momentum, and angular momentum in physics.
Acceleration. Even if a body remains in motion for some time, its acceleration can be zero if the velocity remains constant.
Yes, that is correct. The value of a standard unit of a physical quantity remains constant regardless of the place or time. For example, the standard unit of length, the meter, is the same value whether you are in New York or Tokyo, now or a hundred years ago.

Price will increase, quantity will decrease
The chemical composition is not changed.
price will decrease, quantity will decrease.

Volume is a characteristic property of an object. It is a measurable physical quantity that describes the amount of space an object occupies. The volume of an object remains constant regardless of its location or orientation.
Acceleration. Even if a body remains in motion for some time, its acceleration can be zero if the velocity remains constant.

Caving wood is a physical change because the wood's chemical composition remains the same during the process. The shape and size of the wood may change, but the chemical structure of the wood molecules remains constant.
Yes, that is correct. The value of a standard unit of a physical quantity remains constant regardless of the place or time. For example, the standard unit of length, the meter, is the same value whether you are in New York or Tokyo, now or a hundred years ago.
