What is an aspect of the kinetic-molecular theory and can be used to explain the behavior of plasmas?

1 answer:

4 0

A plasma is a hot ionised gas which has equal number of positively charged particles and negatively charged electrons. Plasma are considered to be the fourth state of matter. Because plasma are made up of charged particles they are affected by both electric and magnetic field. The aspect of the kinetic molecular theory that can be used to explain the behaviour of plasma is that PARTICLES IN MOTION EXCHANGE ENERGY THROUGH ELASTIC COLLISION.

Two unknown molecular compounds were being studied. A solution containing 5.00 g of compound A in 100. g of water froze at a low

Answer:

Compound B has greater molar mass.

Explanation:

The depression in freezing point is given by ;

$\Delta T_f=i\times k_f\times m$ ..[1]

$m=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Mass of solvent in kg}}$

Where:

i = van't Hoff factor

$k_f$ = Molal depression constant

m = molality of the solution

According to question , solution with 5.00 g of A in 100.0 grams of water froze at at lower temperature than solution with 5.00 g of B in 100.0 grams of water.

The depression in freezing point of solution with A solute: $\Delta T_{f,A}$
