Does volume change when substance changes states?
Yes. Usually when a substance freezes, or becomes a solid, it will decrease in volume, causing an increase in density. Water is an exception, which is less dense when it freezes/becomes solid.
When a substance undergoes a phase change it still has a definite A mass B shape C volume D temperature?
C. volume. During a phase change, the substance's volume remains constant even though there may be a change in its mass, shape, or temperature.
What is changed when matter undergoes a phisical change?
When matter undergoes a physical change, its state may change (solid to liquid, liquid to gas, etc.), its shape or size may change, or its physical properties such as density or volume may be altered. However, the chemical composition of the substance remains the same before and after the physical change.
Is pressure a physical change or chemical change?
A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.
What happens when a substance undergoes thermal expansion?
When a substance undergoes thermal expansion, its particles gain energy and move farther apart, causing the substance to increase in volume. This increase in volume is due to the increased average kinetic energy of the particles, leading to the substance taking up more space.
Is thermal expansion a chemical property?
No, thermal expansion is a physical property, not a chemical property. It refers to the tendency of matter to change in shape, area, and volume in response to a change in temperature. It does not involve any change in the chemical composition of the substance.
Does orange juice change volume when poured into a different container?
Orange juice does not change volume when it is poured into a different container. Volume will change if the juice undergoes a process such as concentration.
How can you change density of a substance?
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.
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 can indicate a physical or chemical change?
Physical changes can be indicated by changes in appearance, texture, size, or state of matter without altering the chemical composition. Chemical changes, on the other hand, can be indicated by the formation of new substances, changes in color, temperature, odor, or the production of gas.
Is Exploding a Dynamite a chemical change?
Yes. When dynamite explodes it produces multiple gaseous products. This causes a rapid expansion in volume, which is basically an explosion. Because you have a bunch of gases that you didn't have before, it's a chemical change.
Is volume a physical or a chemical change?
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
