DENSITY & SPECIFIC HEAT OF WATER

 SPECIFIC HEAT – AMOUNT OF HEAT ABSORBED OR LOST FOR 1 GRAM TO CHANGE THE TEMPERATURE BY 1⁰C  WATER HAS A HIGH SPECIFIC HEAT  MEANING, WATER CHANGES ITS TEMOERATURE LESS WHEN HEAT IS ABSORBED OR LOST

HYDROGEN BONDING –THE CULPRIT HYDROGEN BONDING IS THE REASON A CALORIE CAUSES SMALL CHANGE IN TEMPERATURE AS MOST OF THE HEAT IS USED TO DISRUPT H₂ BONDING

AS TEMP DROPS, H₂ BONDS FORM RELEASING A LOT OF ENERGY BODIES OF WATER ABSORB & STORE HEAT IN DAY & SUMMER

CREATES ENVIRONMENT GREAT FOR LIFE AS TEMP FLUCTUATIONS ARE LIMITED ORGANISMS ARE PRIMARILY H₂O & RESIST THEIR OWN TEMP CHANGES

DENITY OF H₂O LESS DENSE AS SOLID THAN LIQUID WHY? HYDROGEN BONDING H₂ BONDS KEEP MOLECULES APART 10% MORE AS SOLID THAN LIQUID

EXPANSION OF H₂O AT FREEZING MAKES LIFE POSSIBLE AS WE KNOW IT ICE INSULATES LIQUID BELOW IN WINTER
