12.
What does cohesion cause a liquid to do?
a)
Cohesion causes the liquid to contract to the smallest possible size and creates an internal pressure at the surface that can resist an external pressure.
b)
Cohesion causes the liquid to expand outward and fill the given container and creates an internal pressure at the surface that can resist an external pressure.
c)
Cohesion causes the liquid to contract to the smallest possible size and creates an internal pressure at the surface that cannot resist an external pressure
d)
Cohesion causes the liquid to expand outward and fill the given container and creates an internal pressure at the surface that cannot resist an external pressure.
