7. A gas-filled weather balloon with a volume of 65.0 L is released at sea-level conditions of

Galina-37 [17]

The balloon will reach its maximum volume and it will burst.

Given:

A weather balloon at sea level, with gas at 65.0 L volume, 745 Torr pressure, and 25C temperature.
When the balloon was taken to an altitude at which temperature was 25C and pressure was 0.066atm its volume expanded.
The maximum volume of the weather balloon is 835 L.

To find:

Whether the weather balloon will reach its maximum volume or not.

Solution:

The pressure of the gas in the weather balloon at sea level = $P_1=745 torr$

$1 atm = 760 torr\\P_1=745 torr=\frac{745}{760} torr = 0.980 atm$

The volume of the weather balloon at sea level = $V_1=65.0L$

The temperature of the gas in the weather balloon at sea level:

$T_1=25^oC=25+273.15 K=298.15 K$

The balloon rises to an altitude.

The pressure of the gas in the weather balloon at the given altitude:

$P_2=0.066atm$

The volume of the weather balloon at the given altitude = $V_2=?$

The temperature of the gas in the weather balloon at the given altitude:

$T_1=25^oC=25+273.15 K=298.15 K$

Using the Combined gas law:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\\\frac{0.980 atm\times 65.0L}{298.15 K}=\frac{0.066atm\times V_2}{298.15K}\\V_2=\frac{0.980 atm\times 65.0L\times 298.15K}{0.066atm\times 298.15 K}\\=965L$

The maximum volume of the weather balloon= V = 835 L

$V < V_2$

The volume of the weather balloon at a given altitude is greater than its maximum volume which means the balloon will reach its maximum volume and it will burst.

The mathematical relationship between gas solubility and pressure is called Henry's Law, solubility = kHPgas where kH is the Hen

Diano4ka-milaya [45]

Answer : The unit of $k_H$ in mol/L.mm Hg is, $1.8\times 10^{-6}mol/L.mmHg$

Explanation :

As we know that the $k_H$ is the Henry's Law constant for argon at $25^oC$ is, $1.4\times 10^{-3}mol/L.atm$

Now we have to determine the unit of $k_H$ in mol/L.mm Hg

Conversion used for pressure from atm to mmHg is:

1 atm = 760 mmHg

So,

$k_H=1.4\times 10^{-3}mol/L.atm\times \frac{1atm}{760mmHg}$

$k_H=1.8\times 10^{-6}mol/L.mmHg$

Thus, the unit of $k_H$ in mol/L.mm Hg is, $1.8\times 10^{-6}mol/L.mmHg$

Select the correct answer from each drop-down menu. How can you reduce air pollution arising from transportation?

Sphinxa [80]

Explanation:

When using public transport vehicles instead of private cars, we emit less pollution. For example in a bus more than 20 people travel, so the pollution per person is lower.

When we increase speed we usually consume more fuel, so avoiding accelerating rapidly we also reduce pollution.

Answer:

a) public transport vehicles.

b) accelerating rapidly.
