The interior of a refrigerator has a volume of 0.600 m3. The temperature inside the refrigerator in 282 K, and the pressure is 101 kPa. If the molecular weight of air is 29 g/mol,
what is the mass of air inside the refrigerator? The ideal gas constant is R = 8.314 J/molK = 0.0821 L atm/mol K.
A) 560 g B) 500 g C) 750 g D) 270 g E) 140 g

Measuring Axillary Temperature
The European Alps have lost ~30% to 40% of surface area and ~50% of volume since the 1850s.
