2. The graph below shows the relationship between pressure and temperature for air, initially at 100.°C and cooling down to absolute zero. Why does the pressure suddenly drop at -183°C and-196°C? Hint: Keep in mind that: (1) air is a homogeneous mixture composed mainly of two gases, and (2) as the temperature falls, certain physical changes will occur to those two gases Pressure Vs. Temperature for Air 300 250 200 150100 5050 100 1e Temperature (â) 3. On the molecular level, why is the pressure of a gas zero at absolute zero?
