What is the definition of sublimation?
- A.
The change of a substance from a solid to a gas
- B.
The change of a substance from a gas to a liquid
- C.
The change of a substance from a liquid to a gas
- D.
The change of a substance from a gas to a liquid
Correct Answer
A. The change of a substance from a solid to a gasExplanation
Sublimation is the process in which a substance transitions directly from a solid to a gas state, bypassing the liquid state. This occurs when the substance is heated and the vapor pressure of the solid exceeds the atmospheric pressure. The molecules gain enough energy to break the intermolecular forces holding them in the solid state and escape into the gas phase. This process is commonly observed in substances like dry ice (solid carbon dioxide) and mothballs (solid naphthalene).Rate this question:

What law states.....mass cannot be created or distroyed?
- A.
The Law of Conservation of Mass
- B.
The Law of Conservation of Energy
Correct Answer
A. The Law of Conservation of MassExplanation
The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products. In other words, the mass of the substances involved in a chemical reaction remains constant before and after the reaction takes place. This law is a fundamental principle in chemistry and is based on the idea that atoms are neither created nor destroyed during a chemical reaction, but are rearranged to form new substances.Rate this question:

Changing state does changes composition and mass
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Changing state does not change composition and mass. When a substance changes state, such as from a solid to a liquid or a gas, its composition remains the same. The molecules or atoms that make up the substance do not change. Additionally, the mass of the substance also remains constant during a change in state. This is because no particles are added or removed, only the arrangement and movement of the particles change.Rate this question:

_______is the force with which a more dense fluid pushes a less dense substance.
Correct Answer
buoyancyExplanation
Buoyancy is the force with which a more dense fluid pushes a less dense substance. When an object is placed in a fluid, it displaces a certain amount of fluid. The fluid exerts an upward force on the object, which is called buoyancy. This force is equal to the weight of the fluid displaced by the object. If the object is less dense than the fluid, it will experience an upward buoyant force greater than its weight and will float. If the object is more dense than the fluid, the buoyant force will be less than its weight and it will sink.Rate this question:
