Sveta_85 [38]3 years ago
7 0

Answer:

Helium can be liquefied, but its condensation temperature is the lowest among all the known substances. Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can explioit these properties.

Explanation:

Sorry if its to long (I could maybe shorten it if needed)

A potato gun beautifully illustrates Law. As you decrease the volume of the air in between two pieces of potato, the
kati45 [8]

<u>Answer:</u> The law that illustrates this is Boyle's Law

<u>Explanation:</u>

  • Boyle's law: This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Mathematically,

P\propto \frac{1}{V}         (at constant temperature and number of moles)

  • Charles' law: This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Mathematically,

V\propto T         (at constant pressure and number of moles)

  • Avogadro's law: This law states that volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.

Mathematically,

V\propto n         (at constant pressure and temperature)

So, when the volume of the air in the gun decreases, the pressure is increased. The inverse relationship between the volume and pressure of the gas is very well illustrated by Boyle's Law.

Hence, the law that illustrates this is Boyle's Law
