Matter
What has matter?
Matter has volume and mass
What is the melting and the boiling point of water?
The melting point 0ºC and the boiling is 100ºC
What is hardness?
Hardness is the a measure of how resistant to pressure or scratching an object is.
What is gravity?
A downward force wich pushes down on the object.
What is the colour?
There are objects or substances can be different colours or different snades of colour. For e amplíe: Amathist Sina purple quartz type.
What is matter?
Matter is all a round us. It is things that we can see, things that we cannot see or things we can taste
Tell me three heat insulators and two heat conductors
Heat conductors can be: copper and iron. Heat insulators can be: wood, plastic and wool.
What are the magnetic properties?
Magnetism is the ability of certain substances to attrack metals
What is average density?
Average density of an objecti What determines whether it float or sinks.
Which are the different states of matter?
Matter has three different states: Solid, liquid and gas.
By who is made un matter? And when they join, what form?
Matter is made up os tiny particles called atoms. Atoms join together to form molecules
Tell me three electrical conductors and three electrical insulators
Electrical conductors can be graphite, gold or copper and electrical insulators can be glass, cotton and rubber.
What is the elasticity?
The elasticity is the ability of a solid object e substance to return to it’s original shape after removing the force which deformed it for example applying pressure to a spring.
What they take acconunt of average density?
The steel that the ship is made of and there is trapped in the body of the ship.
What is average density?
Average density is what determines whether it floats or sink
What is the difference between mass and volume?
Mass is the amount of Matter in an object, however, volume is the amount of space an object or substance occupies.
Tell me all that you now of solubility and tell me an example
This is the hability of a substances to dissolve in another substance and form a solution .
If a substance dissolves well in another substance, it’s soluble.
If a substance does not dissolve well in another substance, it’s insoluble.
An example can be that if you put sugar in water you can for a solution
What is density?
Density is the amount of a mass per unit of volume in a object. Density = mass/volume. It is a measure of how tightly packed the molecules are. Every object has its own density.
Density is measured in kg/
Why do some object float and other sink?
The neason why some object float in water while others sink is because of density and two opposite forces gravity and buoyancy.
How we can identify matter? Explain the two types
We can clasiffy matter into pure substances and mixture. Pure substances only cosists in one type of matter. Mixtures are made up of two or more pure substances. They can be homogeneus or heterogeneus.
Tell me what si tiene difference between melting and boiling point? Then tell me the traduction to spanish
Melting point is when the temperature of an object or a substance increases, it can reach melting point. There traducction to spanish punto una sustancia cambia de sólido a líquido. But boiling point is when the point of a water form example is 100ºC because the liquid change to a gas and there traducction is punto substance is pasa de líquido a gaseoso.
What is the difference between elasticity and magnetic properties?
The elasticity is the ability of a solid object or substance o return to it’s original shape after removing the which deformed it for example, applying pressure to a spring, however, magnetism is the ability of certain substances to attrack metals.
tell me about the difference berreen gravity AND buoyancy
Buoyancy:puso the object to the surface of the liquid
gravity:puso down on the object
