What are 5 physical changes that can occur to a substance?
Melting: The substance changes from a solid to a liquid as heat is applied. Freezing: The substance changes from a liquid to a solid as it loses heat. Evaporation: The substance changes from a liquid to a gas as it is heated. Condensation: The substance changes from a gas to a liquid as it cools. Sublimation: The substance changes directly from a solid to a gas without going through a liquid phase.
Is inertia an extensive property?
No, inertia is an intrinsic property of an object that reflects its resistance to changes in motion. Extensive properties, on the other hand, depend on the amount of substance present, such as mass and volume. Inertia remains constant regardless of the quantity of the substance.
What is the difference between latent heat and specific heat, and how do they affect the temperature changes of a substance?
Latent heat is the energy required to change the state of a substance without changing its temperature, while specific heat is the amount of energy needed to change the temperature of a substance by one degree Celsius. Latent heat affects phase changes (like melting or boiling) while specific heat affects temperature changes. Both play a role in determining how quickly a substance's temperature changes when heat is added or removed.
What is the relationship between mass and the amount of substance in a given object?
The relationship between mass and the amount of substance in an object is that the mass of an object is directly proportional to the amount of substance it contains. This means that as the amount of substance in an object increases, its mass also increases.
What is happening to a substance undergoing thermal energy?
As thermal energy is added to a substance, its temperature increases, causing its molecules to move faster and vibrate more. This can lead to changes in state, such as melting or boiling, depending on the substance and the amount of thermal energy being added.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
Which property of a substance does not change when the amount of the substance changes?
All substances have distinct physical and chemical properties, and may undergo physical or chemical changes. Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter.
Where would a person have the least amount of mass at sea level or the moon?
Neither. Mass, is your total amount of substance, mass never changes.
Which term refers to a property that depends only on the amount of a substance flammabilityextensive intensive reactivity?
The term that refers to a property depending only on the amount of a substance is "extensive." Extensive properties, such as mass and volume, change when the amount of substance changes. In contrast, "intensive" properties, like flammability and reactivity, remain constant regardless of the quantity of the substance.
How is the solubility of a substance calculated at different temperatures?
The solubility of a substance at different temperatures is calculated by measuring the amount of the substance that can dissolve in a given amount of solvent at each temperature. This data is then used to create a solubility curve, which shows how the solubility changes with temperature.
What is enthalpy of fusion vaporization?
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
What changes when substance changes?
When a substance changes, any or all of its properties can also change.
When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
Physical changes in a substance results in?
Physical changes in a substance result in
When a substance changes into a different substance a changes has occurred?
Chemical Change.
What properties changes when substance changes?
When a substance changes, any or all of its properties can also change.
What does this illustrate about the amount of stuff per cm as a substance changes from a liquid to a gas?
As a substance changes from a liquid to a gas, the amount of stuff per cm decreases significantly because gases are less dense than liquids. This is due to the increase in molecular motion and separation in the gas phase compared to the liquid phase.
