Is a physical change what happens when chemical bonds break and new bonds form?
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
Is combining hydrogen and oxygen to make it water is a physical change Is it true or false?
False. Combining hydrogen and oxygen to form water is a chemical change, not a physical change. During this process, the hydrogen and oxygen atoms chemically react to create new substances, resulting in the formation of water molecules. This transformation involves breaking and forming bonds, which is characteristic of chemical changes.
Does a temperature change indicate a physical change?
Yes, it is possible.
True or false the dissolving of sugar in water is an example of a chemial change?
false - it's a physical change. The sugar remains sugar only in solution.
Is it true when a physical change that takes new substances are formed?
No, in a physical change, no new substances are formed. The change only affects the physical appearance or state of the matter, such as size, shape, or phase, but the chemical composition remains the same.
What is the breaking of a glass window is a physical change is true or false?
True.
Is a physical change what happens when chemical bonds break and new bonds form?
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
Is changing the size and shape of pieces of wood a chemical change true or false?
False. Changing the size and shape of pieces of wood is a physical change, not a chemical change. A chemical change involves the alteration of the chemical composition of a substance, while a physical change only affects the physical properties of a substance.
Is combining hydrogen and oxygen to make it water is a physical change Is it true or false?
False. Combining hydrogen and oxygen to form water is a chemical change, not a physical change. During this process, the hydrogen and oxygen atoms chemically react to create new substances, resulting in the formation of water molecules. This transformation involves breaking and forming bonds, which is characteristic of chemical changes.
In physical change matter cannot change its shape true or false?
False. In a physical change, matter can change its shape without changing its chemical composition. Examples include melting, freezing, and dissolving.
Does a temperature change indicate a physical change?
Yes, it is possible.
Is it true or false for A Change In State Is A Physical Change?
True. A change in state, such as from solid to liquid or gas, is a physical change because the substance's chemical composition remains the same and only its physical properties, like shape or state, change.
Is it true that concrete can absorb more force without breaking than a bone can?
yes it is true that bones can sbsorb more force without breaking concrete can
Changing water to ice is an example of a chemical change true or false?
I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.
In a physical changethe makeup matter is changed true or false?
False. In a physical change, the makeup of matter remains the same, only the physical properties like shape, size, or state are altered. No new substances are formed during a physical change.
True or false the dissolving of sugar in water is an example of a chemial change?
false - it's a physical change. The sugar remains sugar only in solution.
Is it usually possible to observe physical objects breaking physical laws?
No, physical objects generally follow physical laws and do not break them. If an object appears to be breaking a physical law, it is more likely due to a misunderstanding or misapplication of the law rather than the object itself violating it.
