Focus On Concepts Section 15.3 The First Law of Thermodynamics 1. The first law of thermodynamics states that the change U in the internal energy of a system is given by U = Q - W‚ where Q is the heat and W is the work. Both Q and W can be positive or negative numbers. Q is a positive number if ________‚ and W is a positive number if ________. (a) the system loses heat; work is done by the system (b) the system loses heat; work is done on the system (c) the system gains heat; work is done by

Corollary 1: The clausius statement of second law of thermodynamics is the first corollary i.e. ‘It is impossible to construct a device operating in a closed cycle that performs no effect other than the transfer of heat from a cooler body to a hotter body.’ The mathematical statement of which is given by; Q1‐Q2=W Q1 W Q2 Corollary 2: It is impossible to construct an engine operating between only two heat reservoirs‚ which will have a higher efficiency than a reversible heat engine operating between

Nitrogen cycle A simple and complete diagram of the nitrogen cycle. The blue boxes represent stores of nitrogen‚ the green writing is for processes that occur to move the nitrogen from one place to another and the red writing are all the bacteria involved. The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation

company either suffers or benefits depending on what kind of economy it is. This will depend on what kind of company it is‚ and what kind of market the business does well in. The Business Cycle is what determines this factor. It is a term used in economics to designate changes in the economy. Timing of the business cycle is not predictable‚ but its phases seem to be. Many economists site four phasesprosperity‚ liquidation‚ depression‚ and recovery. During a period of prosperity‚ a rise in production

where does the water cycle gets its energy from? the water cycle gets the energy from the sun. why do we need the water cycle? since 97% of the earth is covered by salt water we can not drink it. we can remove salt from water but it could be very expensive. how does water get into oceans? when clouds can’t hold any more water it comes as precipitation and lands in the ocean. what is the water cycle made up of? it is made up of six different traits. condensation‚infiltration‚runoff‚ evaporation‚ precipitation
