Document Summary
Lecture 5: properties of water and the chemistry of ocean water. Temperature is a measure of the average of vibration, rotation, and translation energy. High heat capacity: resists changing temperature when heat is added or removed, 1 kcal to change 1 degree. Water has one of the lowest heat capacities of all known substances. A 1-kilogram block of granite can hold more than 1 liter of water (1 liter water = 1 kg). Water molecules are connected with each other by __. Ice has a __ density as the water its made from. Vaporization: 540 calories/gram to break temporary bonds. Whenever heat is added to a system the temperature must go up false. It takes more heat to increase the temperature 1 gram of water from 1 to 100c than it does to turn 1 g of water at 100c into steam. When you add heat and the temperature changes this is called sensible heat.
