1. Sense a. Gas & Liquid Flow: The movement of gas or liquid. Viscosity the state of being thick, sticky, and semifluid in consistency, due to internal friction. Density the degree of compactness of a substance. measurement devices: flow sensor is a device for sensing the rate of fluid flow. anemometer is an instrument for measuring the speed of the wind, or of any current of gas. viscometer is an instrument for measuring the viscosity of liquids. hydrometer is an instrument for measuring the density of liquids. b. Thermal adjective: of or relating to heat; noun: an upward current of warm air, used by gliders, balloons, and birds to gain height. measurement devices: thermometers is an instrument for measuring and indicating temperature. thermocouple is a thermoelectric device for measuring temperature. calorimeter is an apparatus for measuring the amount of heat involved in a chemical reaction or other process. heat flux, sometimes also referred to as heat flux density or heat flow rate intensity is a flow of energy per unit of area per unit of time. thermistor is an electrical resistor whose resistance is greatly reduced by heating, used for measurement and control. thermostat is a device that automatically regulates temperature, or that activates a device when the temperature reaches a certain point.

2. Process Processing is an open source “programming language and integrated development environment (IDE) built for the electronic arts and visual design communities” with the purpose of teaching the basics of computer programming in a visual context, and to serve as the foundation for electronic sketchbooks. Processing includes a “sketchbook”, a minimal alternative to an IDE for organizing projects. Every Processing sketch is actually a subclass of the PApplet Java-class which implements most of the Processing Language’s features. When programming in Processing all additional classes defined will be treated as inner classes when the code is translated into pure Java before compiling. This means that the use of static variables and methods in classes is prohibited unless you explicitly tell Processing that you want to code in pure Java mode.

3. Transform/output chemical reaction A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, often coming about only after the input of some type of energy, viz. heat, light or electricity. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions. Reactions and Energy Chemical energy is part of all chemical reactions. Energy is needed to break chemical bonds in the starting substances. As new bonds form in the final substances, energy is released. By comparing the chemical energy of the original substances with the chemical energy of the final substances, you can decide if energy is released or absorbed in the overall reaction. Exothermic Reactions A chemical reaction in which energy is released is called an exothermic reaction. Exo means “go out” or “exit.” Thermic means “heat” or “energy.” Exothermic reactions can give off energy in several forms. If heat is released in an exothermic reaction, the nearby matter will become warmer. The nearby matter absorbs the heat released by the reaction. The reaction between gasoline and oxygen in a car’s engine is an exothermic reaction.
