Question

The volume of a gas varies directly as its temperature measured in degrees Kelvin (K) and inversely as its pressure. When the temperature of a certain gas is 250 K and its pressure is 76.2 cm of mercury, its volume is 750 cm3. To the nearest cubic centimeter, find the volume of this gas when its temperature is 300 K and its pressure is 73.66 cm of mercury.

Answer 1

same as before but now now there are more variables. varies directly means that it appears across the equal sign, and inversly means that it is across and below:\[Vol_{gas} \alpha \frac{degrees}{Pressure}\]
Now introduce an equal sign and constant as before and solve the constant...
