IDENTIFY MATTER
whats the diference between electrical insulators and electrical conductors?
Electrical conductors allow electricity tontravel through them. Electrical insulators dont allow electricity to travel through them.
What has matter?
Matter has volume and mass.
Why do some objects float?
Objects float because of density, density and buoyancy
what is hardness? What is softest and hardest mineral?
Hardness is the measure of how resistant to preasure of scratching an object is. The softest mineral is talc and the hardest is the diamond.
Can I measure mass in grams and in millilitres?
No, I mesure mass in grams and kilograms.
What is gravity?
Is a down ward force which puses down on the objects
what is the boiling point?
When the temperature of liquid in creases, it can reach boiling point. Thais change the liquid to a gas.
what is volume?
Volume is the amount of space in an object
Why do some objects sink?
some objects float because of density
When do i know If a substance is soluble or insoluble?
If a subtance dissolves well in another subtance, it’s soluble, if not, it’s insoluble.
How can we classify matter?
Whe classify matter in to pure subtance and mixtures.
What is buoyancy?
An upward force which pushes the objects towards the surface of a liquid
What is the formula to calculate density?
DENSITY= mass/volume.
What is wheight?
Is the measure of the force of gravity
What is the average density?
The average density of an object is what determines weather floats or sink average
density takes into account
The steal that the ship is made of
And the air that is trapped in the body of the ship
