(11)Study Guide- Ch. 5 -Physical Properties of Water (2-15-08) Sections 5.4, 5.5, 5.6, 5.7, 1-What is meant by “specific heat?” -specific heat: is the heat capacity of any substance What is “heat capacity” and why is this property of water so important for life on Earth? -heat capacity: (also called specific heat) is the amount of heat required to raise 1 gm of a substance 1* C -water’s specific heat is 1 cal/g/*C, which is much higher than that of most naturally occurring Earth substances -allows for temperature fluctuations of the oceans to be much lower than those of land and air 2-Know the difference between cohesion, surface tension and viscosity, and how they apply to water. -cohesion: strong, repeated bonding among water molecules; gives water the ability to hold itself together -surface tension: because water has good cohesion, the water surface resists stretching or “breaking” which is high surface tension -viscosity: the internal resistance (“stickiness”) of a liquid to motion; water is a low
