7 0

Answer:

Directly counting blood cells or tissue cells by using a hemocytometer can determine the concentration of a known volume. Counting the number of colonies that arise on a pour plate can calculate the concentration by multiplying the count by the volume spread on the pour plate.

What is the major different between the particles in a liquid and a gas of the same substance at the same temperature? a The par
MakcuM [25]

The major difference between the particles in a liquid and a gas of the same substance at the same temperature is that; the particles in the gas are moving faster than the particles in the liquid.

There are three states of matter which are;

  • Solid
  • Liquid
  • Gas

The difference between the states of matter lies in;

  • Degree of inter molecular interaction between molecules in a given state of matter
  • Kinetic energy of the molecules in a given state of matter.

Liquid molecules or particles are slower than gas particles because liquid particles have a greater degree of inter molecular interaction than gas particles.

So, the difference between a liquid and a gas at the same temperature is that; "the particles in the gas are moving faster than the particles in the liquid".
