Answer:

Clouds formed is discussed below.

Explanation:

Clouds are produced when moistened air grows upward. As the breeze increases, it grows more frozen.
Eventually, the wind can't contain all of the water steam in it, and some of the water steam condenses to produce small water droplets. When moistened wind is frozen at the ground, fog is created in the same way.

A gas-filled balloon having a volume of 3.60 L at 1.15 atm and 20°C is allowed to rise to the stratosphere (about 30 km above th

MissTica

<u>Answer:</u> The new volume of the balloon will be 583.5 L

<u>Explanation:</u>

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.

The equation follows:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1,V_1\text{ and }T_1$ are the initial pressure, volume and temperature of the gas

$P_2,V_2\text{ and }T_2$ are the final pressure, volume and temperature of the gas

We are given:

$P_1=1.15atm\\V_1=3.60L\\T_1=20^oC=[20+273]K=293K\\P_2=5.40\times 10^{-3}atm=0.00540atm\\V_2=?\\T_2=-50^oC=[-50+273]K=223K$

Putting values in above equation, we get:

$\frac{1.15atm\times 3.60L}{293K}=\frac{0.00540atm\times V_2}{223K}\\\\V_2=\frac{1.15\times 3.60\times 223}{293\times 0.00540}=583.5L$

Hence, the new volume of the balloon will be 583.5 L
