Matter and its caracteristics

it is any thing that has a mass and a volume

• very active metals

• density

• Matter

• boiling point

it is the amount of matter that the body contains

• melting point

• inactive metals

• volume

• Mass

it is the space that is occupied by the body

• mass

• volume

• matter

• less active metals

it is the mass of unit volume of a substance

• science

• phesycal properties

• density

• mass

calculate the density of a substance whose mass is 35 gm and its volume 25 cm3. it will be:

• 11.4

• 0.04

• 1.4

• 4.1

the mass of copper cube is larger than the mass of aluminum cube although they have the same volume

(a)  

How do we calculate the mass

• mass devide volume

• mass devide density

• mass x volume

• volume x density

density of milk

• 01.3

• 3.00

• 1.03

• 0.03

Give reason:ballons filled with hydrogen or helium rise up in the air carrying flags during festivals

• because the densities of hydrogen or helium are less than the density of air

• hydrogen density is lower than the air density

• helium is compund molecule

• the density of helium is more than the density of the helium

iron is a bad conductor of heat

• True

• false
