What is a psyhical reaction?
A physical reaction, or change, is one that can be observed without changing the chemical composition of the substance. Boiling is a physical change because the substance that is boiling does not change its chemical composition. For example, water is still H2O whether it is boiling or not boiling.
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.
Does the amount of water change the boiling or freezing point of water?
No, the amount of water does not change the boiling or freezing point of water. The boiling point of water is always 100°C (212°F) at sea level, and the freezing point is always 0°C (32°F). The boiling and freezing points are determined by the chemical properties of water, not the amount of water present.
Is boiling does that changes as a physical or chemical?
Boiling is a physical change because the substance is changing from a liquid to a gas without changing its chemical composition.
A substance change from a solid to a liquid at its?
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.
What is the relationship between the heat of vaporization and boiling point of a substance?
The heat of vaporization is the amount of energy needed to change a substance from a liquid to a gas at its boiling point. The higher the heat of vaporization, the higher the boiling point of the substance.
What is a psyhical reaction?
A physical reaction, or change, is one that can be observed without changing the chemical composition of the substance. Boiling is a physical change because the substance that is boiling does not change its chemical composition. For example, water is still H2O whether it is boiling or not boiling.
Is the heat of vaporization the same as the boiling point?
No, the heat of vaporization is the amount of energy required to change a substance from a liquid to a gas, while the boiling point is the temperature at which a substance changes from a liquid to a gas.
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
Is boiling point a physical intensive physical extensive or a chemical?
When a liquid reaches boiling point it goes through a phase change, liquid to gas. Phase changes do not change the nature of a chemical so it is a physical change. This physical change can sometimes be caused by a chemical change though.
Change of substance from liquid to gas?
Boiling
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.
Boiling is one form of the state change?
boiling a phyisical change... but not chemical ( making it a new substance )
Why might the typical boiling point change?
The typical boiling point of a substance can change due to factors such as changes in atmospheric pressure, the presence of impurities in the substance, and variations in the composition of the substance itself. Additionally, the boiling point of a substance can be affected by the altitude at which it is being boiled.
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.
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.
What physical effect can change the boiling of substance?
Pressure
