 The volume of a gas varies inversely as the pressure when the temperature is constant. When the pressure is 15, the volume is 20; what is the volume when the pressure is 20 ? Let v stand for the volume and p for the pressure. Then from pv = k we obtain...  Higher Algebra - Page 362by George Egbert Fisher, Isaac Joachim Schwatt - 1901 - 615 pagesFull view - About this book
