What is the breaking of a glass window is a physical change is true or false?
True.
Is a cake baking an example of a physical change?
When a cake is baked it changes its physical appearance and is thus said to undergo a physical change.However there are many concurrent chemical changes:sugars caramelizeproteins coagulateleavening agents (baking soda etc.) release carbon dioxidestarches, oils and fats oxidize
True or false every chemical or physical change in matter includes a change in energy?
True. Every chemical or physical change in matter involves a change in energy. Energy is either absorbed or released during these processes, leading to a change in the internal energy of the system. This principle is known as the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or converted from one form to another.
Is chemistry a branch of physical science True or false?
Chemistry is considered to be a physical science.
Is most scientific ideas are absolute and not subject to change true or false?
false
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.
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.
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.
When water changes to steam it undergoes a chemical change true or false?
False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.
What is the breaking of a glass window is a physical change is true or false?
True.
When substances are mixed it can result in physical or a chemical change true or false?
true
Is it true are false that a physical change of a substance changes its chemical makeup?
true
Freezing is a change of state true or false?
Yes, freezing is change of state, from liquid to solid. Freezing is a physical change, not a chemical change.
