According to charles's law, if the temperature of a gas increases, the volume a. increases b. decreases c. stays the same d. increases, then decreases

The correct answer is

A.increases

In fact, Charles's Law states that when the pressure of a gas is kept constant, the absolute temperature of a gas and its volume are directly proportional:

where V is the volume and T is the absolute temperature, while k is a proportionality constant. Therefore, we see from the equation that if the temperature increases, the volume of the gas increases as well.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
