Elodia [21]

Crust

Core

Explanation:

For any terrestrial planet, the crust would be the coolest layer and the core would be the hottest layer.

Terrestrial planets or the inner planets made up rocky balls. They have layers that are differentiated.

Typically, they are made up of crust, mantle and the core.

The crust is the outermost layer.

The mantle is the middle layer and core is the inner most layer.

These planets are Mercury, Venus, Earth and Mars.

The outermost layer is usually the coldest part.

The innermost layer is the hottest part which is the core

Answer:

The temperature of the balloon is 46.34 K.

Explanation:

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P * V = n * R * T

In this case:

  • P= 0.76 atm
  • V= 10 L
  • n= 2 moles
  • R= 0.082 \frac{atm*L}{mol*K}
  • T= ?

Replacing:

0.76 atm* 10 L= 2 moles* 0.082 \frac{atm*L}{mol*K} *T

Solving:

T=\frac{0.76 atm* 10 L}{2 moles* 0.082\frac{atm*L}{mol*K}}

T= 46.34 K

<u><em>The temperature of the balloon is 46.34 K.</em></u>
