In the demonstration shown below left, a
soft drink can containing a small amount of
water is heated over a Bunsen burner. The
can is then overturned with the opening of
the can placed in cold water (below on the
right). After being placed in the cold water,
the can quickly crushes inward. Explain the
result of this experiment. Why did the soft
drink can implode?
the bottom where the air can escape is inside the water & air moves up so the water was acting like a lid to the can, no air being able to move in.
How is flow rate related to viscosity?
the more vicious the fluids are, the thicker they are, the flow rate is slower.
What is the effect of temperature on viscosity in liquids? In gases?
What is the difference between adhesion and cohesion?
Adhesion is attraction or joining of two different objects or fluids to
Cohesion refers to the
strength with which the particles of
an object or fluid attract each other.
Why do fluids adhere to certain surfaces?
Water molecules have polarity, which means that one end of each
molecule is slightly positive, and the other end is slightly negative
