The potential of electrons in a circuit can be increased by
flowing through the conducting wires
the action of a battery
passing through a circuit element
water pressure

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

Can you match these to the correct definition

Convection currents are caused by differences in what two things?
