Write any five properties of colloidal sollution

Explanation:

Properties of a colloid

• A colloid is a heterogeneous mixture.

• The size of particles of a colloid is too

small to be individually seen by naked

eyes.

• Colloids are big enough to scatter a

beam of light passing through it and

make its path visible.

• They do not settle down when left

undisturbed, that is, a colloid is quite

stable.

• They cannot be separated from the

mixture by the process of filtration. But,

a special technique of separation known

as centrifugation (perform activity 2.5),

can be used to separate the colloidal

particles.

Hope this helps

plz mark as brainliest

i believe it is 40–40–20%

explanation:

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
