Regular medicinal use of marijuana is a fairly new practice. For that reason, its effects on people who are weakened because of age or illness are still relatively unknown. Older people and those suffering from diseases such as cancer or AIDS could be more vulnerable to the drugâs harmful effects.
For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.
Pressure-density relationship. The density of liquid water tends towards an integral 6 th power relationship with respect to pressure. where P is the pressure (MPa), P 0 is 378 MPa, T is the temperature (K), T 0 is 85 K and.s the density (g/mL). This relationship is shown below (P' is the scaled pressure, that is, the left side of the above expression) as the dashed lines, with the colored lines being the experimental data. The lines for 20 Â°C - 60 Â°C fit well but the power increases from 6 at lower and higher temperatures.
