Plays a big part in sleep and ‘feeling good’. Endorphin The senses, especially pain, emotional and physical distress. A lot of the high you get from exercise comes from endorphins.

butane.chem.uiuc.eduTemperature Dependence As with other gases, the solubility of carbon dioxide in water decreases as the temperature increases. You can see this for yourself by observing what happens when you heat a can of soda. As the temperature of the oceans increases with increasing global temperature (caused by greenhouse gases), carbon
