Global Hydrological Cycle Thermodynamic properties of water Humidity Water Vapor in the Air Vapor pressure Absolute humidity The mixing ratio Specific humidity Relative humidity Relative Humidity. Controlled atmosphere storage refers to the constant monitoring an d adjustment of the CO and O levels within gas tight stores or containers The gas mixture will constantly change due to metabolic activity of the respiring fruits and vegetables in t LIMITATION OF FIRST LAW OF . THERMODYNAMICS. It does not give information concerning feasibility of a thermodynamic . proces. .. why. NOT EXPLAINED BY FIRST LAW. It tells that work obtained is equal to heat absorbed but in actual heat absorbed can not be completely converted into work. Heat transfer processes. convection. conduction. . . radiation . . Physics of the atmosphere. the ozone layer. Greenhouse effect. climate change. 1. Thermodynamics- review. Thermodynamics. is the science dealing with heat, work, and energy and the trans-formation of one into the other. Physics Lecture Notes. The Laws of Thermodynamics. FOUNDRY: It requires about 289 Joules of heat to melt one gram of steel. In this chapter, we will define the quantity of heat to raise the temperature and to change the phase of a substance. . The Basics. The brief definition of Thermodynamics is . the science concerned with the relations between heat and mechanical energy or work, and the conversion of one into the other: modern thermodynamics deals with the properties of systems for the description of which temperature is a necessary coordinate. Introduction. Zeroth Law of Thermodynamics. If objects A and B are separately in thermal equilibrium with a third object C, then A and B are in thermal equilibrium with each other. . Temperature . T.

Boundaries – fixed or moveable. Atmosphere Essential Question: How are we changing our atmosphere? Learning Goals: Be able to identify the layers of the atmosphere. Describe what molecules make up the atmosphere. Atmosphere Atmosphere ATMOSPHERE Composition of the Atmosphere The atmosphere is comprised of a variety of gases: Major Constituents (99%): Nitrogen (N): 78% Oxygen (O 2 ): 21% Trace Constituents: Other: 1% Heat transfer processes. convection. conduction. . . radiation . .
