Condensation is the change in state of matter from gas to liquid.
1) you want to increase friction when it gets cold. If you're outside and it's really cold, you're going to rub your hands to warm them up, therefore friction is increasing
I'm not do sure about decreasing.
Strong acids have a higher PH while weaker acids have a lower PH
I'm other words, acidic bases have a higher PH whilst less acidic bases have lower PH
