chemical composition and water

1. Cohesive Force And Adhesive Force Of Water

1.1. ★water molecules are attached to each other through cohesive force ★water molecules also attached to the other surface through adhesive force ★both forces produce capillary action which allow water to enter and move along narrow spaces,such as xylem tube

2. Specific Heat Of Water

2.1. ★water has a high specific heat capacity of 4.2 kJ kg-¹C°-¹ ★4.2 kJ heat required to raise temperature of one kilogram water by 1C° ★water absorb a lot of heat energy with a small rise in temperature. this characteristics important to maintain body temperature of organism.

3. Polarity Of Water

3.1. ★inorganic compound which is consisting hydrogen (h) and oxygen (o) ★water is polar molecules because shared electron between oxygen and hydrogen will be attracted to oxygen and cause electronegative ★this polarity will produce hydrogen bond and allows water become universal solvents ★the universal solvent properties of water allows water to sollute in glucose and electrolyte
