Because there is a law of nature that says that matter (mass) can neither be created nor destroyed.

However, Einstein proved that mass and energy are actually the same thing (E=MC2), so mass can be turned into energy and energy can be turned into mass.

How will the mass of a pure substance be affected when the volume is increased?

The mass of a pure substance will remain constant even if the volume is increased. The mass of a substance is an intrinsic property that does not change with changes in volume.


What is always the same no matter how much of the substance you have?

The chemical composition or properties of the substance remain constant regardless of the quantity present.


As long as conditions such as what do not change the density of a substance dose not change?

As long as the temperature and pressure remain constant, the density of a substance will not change. Density is determined by the mass of a substance and its volume, and as long as these factors remain constant, the density will remain the same.


Does the melting point and freexing point change depending on the mass?

The melting point and freezing point of a substance generally do not change based on the mass of the sample. They are intrinsic properties of the substance that remain constant regardless of the amount being measured.


Do properties remain the same regardless of the amount of the substance?

Intensive properties remain the same with a change in the amount of a substance - for example: temperature and density Extensive properties do not remain the same with a change in the amount of a substance - for example: mass and volume


Why does a substance have a constant flow rate if all variables remain constant?

because i have bstl


Is density a fixed quantity or a variable quantity for a particular compound?

Density is a fixed quantity for a particular compound because it is calculated using the formula mass divided by volume, which gives a specific value for a given substance. This value will remain constant as long as the mass and volume of the substance remain unchanged.


Which variables must be kept constant for Boyle's law to hold?

Temperature and the amount of gas (moles) must be kept constant for Boyle's law to hold true. This means the pressure and volume of a gas are inversely proportional provided the temperature and amount of gas remain constant.


Does mass remain constant?

Yes, Mass remains constant because the definition of mass does not mean weight. Mass means the amount of room and object takes.


Why the mass of a substance is constant everywhere?

Because the mass is not dependent on the gravitational influence.


For any pure substance the boiling point and melting point will always remain?

The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
