Answer:

2. Volcanoes

Explanation:

The interior of some planets (e.g earth) contains some hot flowing fluids called lava which has a very high thermal energy. The lava as a means of escaping the confinement within the planet, burst out by creating an opening through the ground to the surface of the planet to release the energy (lava).

This process in which the energy is released to the surface of the planet is termed volcanic eruptions. Which occurs majorly in some susceptible regions of the earth.

The openings in the ground that release energy from deep inside the planet is thus called volcanoes.

A gas sealed in a drum container occupies 7.70 L at a sizzling 325C degrees. What will the volume be if the drum is quickly chi
grigory [225]

The volume of the drum after chilled quickly is 3.6 L.

<u>Explanation:</u>

As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.

$\frac{V1}{T1} = \frac{V2}{T2} \\

After chilling the drum, the volume will get reduced and it can be found as,

V2 = $\frac{V1T2}{T1}

     = $\frac{7.7 L \times 282 K}{598 K}

      = 3.6 L

Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.

Is it convection conduction or radiation "air travels this way" please answer
Sphinxa [80]
Radiation is the only way heat is transferred that can move through the relative emptiness of space. All other forms of heat transfer require motion of molecules like air or water to move heat.
