Is mixing iron fillings with sand a physical change?
Yes, mixing iron fillings with sand is a physical change. This is because no new substances are formed during the mixing process; the iron fillings and sand retain their original properties and can be separated back into their individual components.
Give one advantage of making the frame from smart alloy instead of an ordinary metal?
It can go back to its original shape when it is heated.
What happens to the particles in distillation?
In distillation, the particles in a liquid mixture are separated based on their boiling points. When the mixture is heated, the component with the lower boiling point vaporizes first, rises, and condenses back into a liquid in a separate container. The remaining components are left behind in the original container.
Can methylated spirit be separated with a funnel?
Yes, methylated spirit can be separated using a funnel. It can be separated by the process of distillation where the components are boiled off at different temperatures and condensed back into separate liquids.
Why does the distillate needs to be cooled?
Cooling the distillate is necessary to condense it back into a liquid form. This is important because distillation involves vaporizing the liquid to separate its components, and cooling the distillate allows the separated components to be collected in liquid form for further use.
Do components of a mixture maintain their original properties?
Yes, that is why it is a mixture. It can be separated back out to the original components (although this is sometimes difficult).
Can all mixtures be changed back into the substances from which they are created?
Yes, because the substances can be separated apart physically.
Can you separate potassium hydroxide?
No, potassium hydroxide cannot be easily separated back into its original components once it has been mixed together. It is a fully reacted compound.
How can crude oil be separated into its components?
Crude oil can be separated into its components through a process called fractional distillation. This involves heating the crude oil to a specific temperature where different hydrocarbons in the mixture evaporate at different rates due to their varying boiling points, allowing them to be collected separately as they condense back into liquid form.
Is mixing iron fillings with sand a physical change?
Yes, mixing iron fillings with sand is a physical change. This is because no new substances are formed during the mixing process; the iron fillings and sand retain their original properties and can be separated back into their individual components.
Give one advantage of making the frame from smart alloy instead of an ordinary metal?
It can go back to its original shape when it is heated.
Is sand added to water a mixture or pure substance?
Sand added to water is a mixture. Sand is a solid substance composed of tiny particles, while water is a liquid. When sand is added to water, it does not undergo a chemical change and can be separated back into its original components.
What is the difference between an alloy and a smart alloy?
An alloy is a mixture of two or more different metals or non metals whiles A smart alloy is an alloy that returns to it original shape when heated................................... An alloy is a mixture of a metal with at least one other element. A smart alloy is an alloy that will make one change when effected by an outside force (e.g.: heat, pressure, etc.) and will change back, whether that is a change in shape or produced voltage.
Why is light spilt into different colours?

Is coffee dissolving irreversible or reversible?
Irreversible... You could distill a cup of prepared coffee - until all the water boils off, but you would never get back the original coffee powder, or granules.
