properties of H2O

Buoyancy . Archimedesʼ principle states that there is an upward force on the body when immersed in water equal to the amount of water that has been displaced by the body
Buoyancy The ability to float in water results from the body possessing a specific gravity less than that of water.
Hydrostatic pressure Water exerts pressure that is perpendicular to the body and increases in proportion with the depth of immersion.
Resistance Water molecules tend to attract to each other and provide resistance to movement of the body in the water.
Resistance by water increases in proportion to speed of motion.
Specific Gravity The computation for the specific gravity of water is equal to 1.
The human body varies based on size and somatotype but typically has a specific gravity of less than 1 (average .974). Therefore, a person will generally float when fully submerged in water.
The specific heat is the measure of the ability of a fluid to store heat.
specific heat is calculated as the amount of thermal energy required to increase the fluidʼs temperature by one unit.
Water can store four times the heat as compared to air.
Waterʼs thermal conductivity is approximately 25 times faster than air at the same temperature.
The total drag force is comprised of profile drag, wave drag, and surface drag forces.
total drag force is a hydromechanic force exerted on a person submerged in water that normally opposes the direction of the bodyʼs motion.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
