The formula used for determining gas pressure, volume and temperature interaction would be PV=nRT.
<span>• What is the temperature in Kelvins?
</span>You already right at this part. Kelvin temperature formula from celsius should be:
K= C+273.15=
<span>K= 27 +273.15 = 300.15
It is important to remember that the formula in this question is using Kelvin unit at temperature, not Celcius or Fahrenheit.
</span>
<span>• Assuming that everything else remains constant, what will happen to the pressure if the temperature decreases to -15 ºC?
</span>In this case, the temperature is decreased from 27C into -15C and you asked the change in the pressure.
Using PV=nRT formula, you can derive that the temperature will be directly related to pressure. If the temperature decreased, the pressure will be decreased too.
<span> If you increase the number of moles to 6 moles, increase temperature to 400K and reduce the volume to 25 L, what will the new pressure be?
</span>PV=nRT
P= nRT/V
P= 6 moles* <span>0.0821 L*atm/(mol*K) * 400K/25L= 7.8816 atm</span>
1) <span>Step 5 A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis. Inorganic carbon is turned into organic.
2) </span><span>Step 1 A caterpillar gets the carbon by eating the tree's leaves. Caterpillar use carbon for energy.
3) </span><span>Step 3 A bird gets the carbon by eating the caterpillar. Organic carbon shifts from one animal to another
4) </span><span>Step 4 The bird flies into a building and dies instantly. It falls to the ground.
5) </span><span>Step 2 The bird decomposes and the carbon is added to the atmosphere. Organic carbon turns into inorganic.
