In the ideal gas law the proportionality constant is represented by the letter r (rather than the generic k). What is the volume at 132 °c? 1.06 x 103 mmhg variables equation name:

Explain Why You Are Sure That It Is Colder.

The unit of mm hg is also called the torr, so 1 atm = 760 torr. Of the three principal states of matter (gas, liquid, solid), gases show behavior that is most easily connected to molecular motion. All work is shown as well as how to set up each problem!
