BIOL 111 Lecture Notes - Lecture 3: Evaporative Cooler, Heat Capacity, Lysozyme
Document Summary
Oxygen has slightly negative charge while hydrogen has slightly positive. Water has high specific heat and high heat of vaporization. Heat is a form of energy that is dependent on volume: unit is a calorie (c, amount of heat required to move temp of 1 c of 1 g, 1j= . 239 cal. Takes a lot of heat for temperature change. Heat of vaporization- 1 g of substance from liquid to gas. Evaporative cooling- as water evaporates it removes a lot of heat, sweating stabilizes temp. Water expands as a solid=less dense, forms a water lattice, <4 c. Cytoplasm is a concentrated aqueous solution w/ many small molecules and ions and very large molecules, such as proteins. Molecular mass- mass of all atoms in one molecule.
