What are the law of conservation of mass as it relates to phase changes?
The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction. During phase changes, such as melting or boiling, the mass of the substances involved remains the same before and after the change. This means that the total mass of the substances in a closed system will always remain constant.
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
Are all changes in states for element reversible?
Not all changes in states for elements are reversible. Physical changes, such as melting or boiling, are typically reversible, allowing the substance to return to its original state. However, chemical changes, like combustion or rusting, result in new substances and are generally irreversible. Therefore, the reversibility of a state change depends on whether it is a physical or chemical change.
What is the law of constant mass in chemical changes?
The law of constant mass, also known as the law of conservation of mass, states that the total mass of substances before a chemical reaction is equal to the total mass of the substances after the reaction. In other words, mass cannot be created or destroyed in a chemical reaction, only rearranged. This principle is a fundamental concept in chemistry.
What is the law that states that mass is neither created nor destroyed during chemical reactions or physical changes?
The law of conservation of matter states that matter cannot be created or destroyed in an ordinary chemical reaction.
Pressure changes have no effect on the entropy of substances in the blank or blank states?
Pressure changes have no effect on the entropy of substances in the solid or liquid states. Entropy is primarily affected by temperature changes and phase transitions rather than pressure variations in these states.
What is it called when the three states change?
changes of state are called phase changes.
How are the state changes of similar to the states changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
How mass conserved during chemical and physical changes?
the of conservation of energy states that energy neither is created or destroyed it changes states the of conservation of mass states that mass neither is created or destroyed it only changes state
When matter undergoes a physical or chemical change the amount of mass changes or stays the same?
In physical changes, the amount of mass stays the same because no new substances are formed. In chemical changes, the amount of mass stays the same due to the law of conservation of mass, which states that mass cannot be created or destroyed, only rearranged into different substances.
How are the states changes of water similar to the state changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.

When a substance changes states at different temperature and pressure this is called?
pasterisation
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
What were the changes to the contition of the US called?
Changes to the Constitution are called amendments. Three-fourths of the states or 38 must ratify amendments for them to become part of the Constitution.
What are some things that have melting points?
All substances have a melting point.Water, for example, has a melting point. It is simply the temperature at which a substance changes states to a liquid.
Are all changes in states for element reversible?
Not all changes in states for elements are reversible. Physical changes, such as melting or boiling, are typically reversible, allowing the substance to return to its original state. However, chemical changes, like combustion or rusting, result in new substances and are generally irreversible. Therefore, the reversibility of a state change depends on whether it is a physical or chemical change.
