Which of the following is true about polarity?
cohesion
because the attraction between water molecules is so strong that they stick together and hold the paper clip up
false
true
True
Water is more polar than alcohol so it takes more energy to boil or evaporate.
the droplets clung together and formed a dome or bubble on the surface of the penny
surface tension
A water bug being able to walk on the surface of the water is an example of
cohesion
because the attraction between water molecules is so strong that they stick together and hold the paper clip up
false
true
True
Water is more polar than alcohol so it takes more energy to boil or evaporate.
the droplets clung together and formed a dome or bubble on the surface of the penny
surface tension
A pond will require more energy to boil than the ocean
cohesion
because the attraction between water molecules is so strong that they stick together and hold the paper clip up
false
true
True
Water is more polar than alcohol so it takes more energy to boil or evaporate.
the droplets clung together and formed a dome or bubble on the surface of the penny
surface tension
Oceans take a long time to heat up because water is so reflective that the heat rays bounce off.
cohesion
because the attraction between water molecules is so strong that they stick together and hold the paper clip up
false
true
True
Water is more polar than alcohol so it takes more energy to boil or evaporate.
the droplets clung together and formed a dome or bubble on the surface of the penny
surface tension
In our lab about surface tension, why was the paper clip able to float on water?
cohesion
because the attraction between water molecules is so strong that they stick together and hold the paper clip up
false
true
True
Water is more polar than alcohol so it takes more energy to boil or evaporate.
the droplets clung together and formed a dome or bubble on the surface of the penny
surface tension
In the lab where we put water droplets on a penny, what is the word that describes the water droplets attraction to each other and desire to keep its droplet form?
cohesion
because the attraction between water molecules is so strong that they stick together and hold the paper clip up
false
true
True
Water is more polar than alcohol so it takes more energy to boil or evaporate.
the droplets clung together and formed a dome or bubble on the surface of the penny
surface tension
A water droplet requires less energy to boil than a river.
cohesion
because the attraction between water molecules is so strong that they stick together and hold the paper clip up
false
true
True
Water is more polar than alcohol so it takes more energy to boil or evaporate.
the droplets clung together and formed a dome or bubble on the surface of the penny
surface tension
What happened as you kept adding water droplets on top of the penny?
cohesion
because the attraction between water molecules is so strong that they stick together and hold the paper clip up
false
true
True
Water is more polar than alcohol so it takes more energy to boil or evaporate.
