1. A volume of 120.0 liters of a gas is prepared at a pressure of 400.0 mm Hg and a temperature 100.0 °C. The gas is placed into a tank under high pressure. When the tank cools to 10.0°C,
the pressure of the gas is 20.0 mm Hg. What is the volume of the gas?

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the final volume by using the combined ideal gas:

In such a way, by solving for the final volume, V2, we obtain:

Now, by plugging in the pressures, temperatures in Kelvins and initial volume, we will obtain:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
