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.
What is the relationship between temperature air pressure and density in the layers of the earth's atmosphere? With increasing altitude in the atmosphere, pressure decreases and so does density. Temperature varies depending on the layer in which the air is.
