What happens to the pressure if you double the volume?
What happens to the pressure if you double the volume? If volume increases, then pressure decreases and vice versa, when the temperature is held constant. Therefore, when the volume is halved, the pressure is doubled; and if the volume is doubled, the pressure is halved. Why is temperature directly proportional to volume? So, that means […]
