So the answer is A
I’m pretty sure is “his” which will be C
There are different kinds of experiment. The relationship between volume and temperature is that As temperature goes up, volume also goes up when pressure is held constant.
- As seen in the data, as the temperature often increases the volume in each gas therefore still increases slightly.
<h3>What is the relationship between volume and temperature?</h3>
Note that the volume of any gas or substance is said to directly proportional to its temperature.
Charles's law gave the theory that the volume of a given amount of gas is certainly proportional to its temperature using the kelvin scale when the pressure is known to be constant.
