Imagine each of those as a drop of sweat that will evaporate taking a bit of your body heat away. So sweat helps cool you down two ways. First, it makes your skin feel cooler when it's wet. And when it evaporates it removes some heat.

What volume would a 0. 250 mole sample of h2 gas occupy if it had a which a a pressure of 1. 70 atm and a temperature of 35 C?

frosja888 [35]

The volume of 0. 250 mole sample of $H_{2}$ gas occupy if it had a pressure of 1. 70 atm and a temperature of 35 °C is 3.71 L.

Calculation,

According to ideal gas equation which is known as ideal gas law,

PV =n RT

P is the pressure of the hydrogen gas = 1.7 atm
Vis the volume of the hydrogen gas = ?
n is the number of the hydrogen gas = 0.25 mole
R is the universal gas constant = 0.082 atm L/mole K
T is the temperature of the sample = 35°C = 35 + 273 = 308 K

By putting all the values of the given data like pressure temperature universal gas constant and number of moles in equation (i) we get ,

1.7 atm×V = 0.25 mole ×0.082 × 208 K

V = 0.25 mole ×0.082atm L /mole K × 308 K /1.7 atm

V = 3.71 L

So, volume of the sample of the hydrogen gas occupy is 3.71 L.

Why is the mesosphere colder than the troposphere

mezya [45]

The mesosphere is the coldest of the atmospheric layers. In fact it is colder than the Polar regions of the Earth cold enough to freeze water vapor into ice clouds. As you increase in altitude, temperature decreases The thermosphere is the layer to which this pattern does not apply.
