What else can I help you with?
Which action would result in a chemical change?
A new substance is produced. Bubbles are given off (fizzing), which shows that a gas has been produced. Color changes. Turbidity (cloudiness) heat/light given off. A sound is produced/an explosion occurs etc
What do you call the heat given to or given up from a substance?
The heat given to or given up from a substance is called heat transfer.
When a substance change into a different substance a change has occurred?
Chemical Change.
A chemical change is a change in the what of a substance?
burning the substance.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
At any given location the physical properties of a substance do not change?
no
How easily a substance will change chemically in a given situation?
Reactivity
Do the physical properties of a substance change At any given location?
True
What is meant by a characteristic property of a substance?
A characteristic property of a substance is a unique and specific attribute that is inherent to that substance and helps to identify and distinguish it from others. These properties remain constant regardless of the amount or form of the substance and can be used to determine its identity.
What are properties of a substance that will never change?
weight, volume, density, mass
Which action would result in a chemical change?
A new substance is produced. Bubbles are given off (fizzing), which shows that a gas has been produced. Color changes. Turbidity (cloudiness) heat/light given off. A sound is produced/an explosion occurs etc
Do the physical properties substance change At any given location?
No, the physical properties of a substance do not change at a given location unless there is a change in temperature, pressure, or state of matter. These properties include characteristics like density, color, odor, melting point, boiling point, and solubility.
What is a chemical change said in one sentence?
Any instance in which the chemical formula of a given substance is changed, resulting in the formation of a new substance.
What is the name given to the change in state from gas to liquid?
When a substance is liquid and it changes to gas, we call that boiling.
What is important is physical change?
The importance of physical change is that :-1) No new substance is formed.2) It is a temporary change.3) It is easily reversible.4) Very little heat energy is absorbed or given out.The mass of a substance does not alter in a physical change.
What happens to the density of a given substance if you increase the amount of substance that you have?
The density of a substance remains constant regardless of the amount of the substance. Density is an intrinsic property of a material and is determined by its mass and volume. Increasing the amount of substance will only change the mass and volume proportionally, thus keeping the density constant.
What do you call the heat given to or given up from a substance?
The heat given to or given up from a substance is called heat transfer.
