Presentation transcript:

Adhesion- When a substance sticks to another surface. Comparison: When you get out of a pool and the water sticks to your body or your towel.

Capillary action- This is when a liquid is in touch with a solid and rises in a tube. Comparison: Before you decide to go swimming, and take the temperature of the pool either the thermometer goes up or down.

Cohesion- Is when a substance sticks to the same substance. Comparison: When the pool is filled with water.

Hydrogen bond- Forms when the water is polar. Comparison: When you jump in the water it warms up fast.

Polarity- Properties of a molecule that different charges and are not balanced. Comparison: The water would need polarity to heat up the water.

Significance of Water’s density- The thickness or compactness of water. Comparison: How we can’t run very fast in a pool.

Significance of Water’s Specific Heat- Uses calories to raise the temperature of one gram. comparison: The water in the pool starts to heat up.

Surface Tension- Properties of a liquid towards a small space of the water where there is an unequal force. Comparison: When a floatation devise stays on top of the water.

Universal Solvent- It dissolves anything Comparison: When you put chlorine blocks into the pool they dissolve.

Water Cycle- The process of water through land to air Comparison: Water can evaporate from the pool and rain fills the pool.

Fun facts- 1.A healthy person can drink about three gallons (48 cups) of water per day. 2.Water intoxication is most likely to occur during periods of intense athletic performance. 3.Much more fresh water is stored under the ground in aquifers than on the earth’s surface. 4.The average person in the United States uses anywhere from gallons of water per day. Flushing the toilet actually takes up the largest amount of this water. 5.The weight a person loses directly after intense physical activity is weight from water, not fat.
