A collected gas has a pressure of 778mmHg and a temperature of 47.0C. What would be the new pressure at standard temperature
lesantik [10]

Answer:

= 664.10 mmHg

Explanation:

According to pressure law the pressure of a fixed mass of a gas is directly proportional to the absolute temperature.

Therefore;

P1/T1 = P2/V2

Standard temperature is equal to 0°C, which is 273.15 K.

In this case;

P1/T1= P2/T2

P1 = 778 mmHg

T1 = 47.0 + 273 K

    = 320 K

P2 = ?

T2 = 0° C = 273.15 K

P2 =P1T2/T1

    = (778 × 273.15)/320 K

    <u>= 664.10 mmHg</u>

Explain the relationship between the loss of Arctic ice and the sustainability of human populations
Delicious77 [7]

Answer:

As the ice melts in the arctic regions, the arctic sea levels and the other oceans stay the same. The weather however changes when this happens and results to the Greenland's melting ice sheet adding another 20 feet to sea level rise.

In summary, the melting of polar ice caps effects would result in sea levels rising around 220 feet or more worldwide.

This will then lead to destruction of lives, houses and properties due to water submersion.
