Melting Point of water is
100 degrees Celsius
0 degrees Celsius
0 degrees Fahrenheit
On a hot, summer day, water droplets often form on the outside of a cold glass of water. The water droplets form when water vapor in the air
loses heat on the cold glass
reacts with the chemicals in the air
gains energy from sunlight
is moved about quickly by wind
After taking a shower, a student observed water droplets condensing on the bathroom mirror. Water condenses on the mirror because the mirror -
reflects light energy
is cooler than the air
is a large, flat solid
can easily be removed
The following are physical characteristics of pure water except...
low surface tension
colourless
tasteless
liquid at room temperature
When water freezes in the ocean, the ice floats to the surface. What property explains this phenomenon?
water expands when it freezes, making ice less dense than water
water compacts when it freezes, making ice more dense than water
hydrogen bonds in water push the ice to the surface
ice is afraid of water, and avoids it
If this is a floating ice sheet, which property of water is this polar bear relying on?
Surface Tension
Cohesion
Adhesion
Density
The diagram shows daddy longlegs on the surface of water.
The daddy longlegs able to stay afloat on water is a result of ..
