Because for gas law problems, you cannot have a negative value for temperature. The Kelvin scale is an absolute temperature scale, meaning it goes from 0 upward and is always positive.

It will go up. If you hold the pressure constant and increase the temperature, the volume will go up. If you decrease the pressure and hold the temperature constant, the volume will also increase.
