The severity of the disease manifestations depends on the number of microbes present in the body. Smaller is the number of microbes in the body, lesser are the symptoms of a disease. On the contrary, if microbe exists in large number in the body, disease can be severe and life-risking.

- Second Law of Motion:
The second law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.
The quantity of motion in a body depends on the product of mass and velocity of the body termed as momentum.
The momentum (p) of a body is defined as the product of its mass (m) and velocity (v) and has the same direction as that of the velocity. Its SI unit is kilogram metre per second (kg m s−¹).
Momentum = mass × velocity
p = m × v
Momentum has both magnitude as well as direction; hence it is a vector quantity.
Momentum of a body at rest is zero.

The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container.
Diffusion refers to the process of particles moving from an area of high concentration to one of low concentration. The rate of this movement is a function of temperature, viscosity of the medium, and the size (mass) of the particles. Diffusion results in the gradual mixing of materials, and eventually, it forms a homogeneous mixture.
Not only do gaseous particles move with high kinetic energy, but their small size enables them to move through small openings as well; this process is known as effusion. For effusion to occur, the hole’s diameter must be smaller than the molecules’ mean free path (the average distance that a gas particle travels between successive collisions with other gas particles). The opening of the hole must be smaller than the mean free path because otherwise, the gas could move back and forth through the hole.
Effusion is explained by the continuous random motion of particles; over time, this random motion guarantees that some particles will eventually pass through the hole.
