Explanation:

Pressure is the force per unit area pounded onto the surface of a container of a gas or liquid. It's interesting to notice that the units of pressure (force/area) are the same as the units of energy density (energy/volume). This gives rise to the interesting result that the pressure at the centers of stars that we think should be sustaining the star against collapse actually attracts more pressure, at high enough pressures, and contributes to collapse.

Temperature is proportional to the energy per degree of freedom of a system; more abstractly, it is a measure of how much entropy change, dS, is associated with a transfer of heat, dQ:

dS = dQ/T.

If To < T1, dS0 = dQ/T0 > dQ/T1 = dS1

That means that even though the total heat transferred within the total system is 0, the total entropy has increased. Since heat flows from higher to lower temperatures, entropy keeps increasing.

For the so-called "perfect gas" model, the pressure, P, satisfies:

P = N * k* T

where N is the number of gas molecules

and k = Boltzmann's constant.

\huge\mathbb\red{\boxed{Answer}}

Pressure is the continuous physical force exerted on an object by something in contact with it.Temperature is the degree of heat present in a substance or object.

\tt\blue{Relationship\:b/w\:Temperature\:and\:pressure}

The temperature between temperature and pressure of a gas is stated by Gay Lussac's pressure temperature Law.

\tt\blue{Gay-Lussac's\:Law:}

  • The pressure P of a fixed mass of gas held at a constant volume is directly proportional to its Kelvin temperature.
  • As the temperature of a particular system goes up, the temperature of that system also goes up, and vice versa.
  • V and n are constant.
  • P1/T1=P2/T2.
