PPT-Pressure and Density

What is pressure what is density and how do we measure them Who contributed to our current ideas and theories about pressure Where can we see pressure measured on a daily basis Important Questions. . . . Finish Ch. 11 . Liquids . (Ch. 13. ). Ch 13 (Liquids). First, concept of . density. (in Ch 12, everything else of which we are skipping). Density = . mass . volume. Density measures how squished up the matter is, . “water, water every where, nor any drop to drink…” - Coleridge. What is a liquid?. Liquid is one of the four states of matter. What are the other three?. A liquid is incompressible . That means that you won’t change its volume no matter how much you squeeze it. What . is an advantage of composites that aids in lowering maintenance costs?. What is a potential disadvantage of composites in a hot climate or conditions?. Describe the care maintainers must utilize with paint strippers on composite materials?. What is the axis of flight that runs from the nose tip to the tail of the aircraft?. Describes what happens to an aircraft when the CG moves rearward.. When flaps are extended during takeoff, what do they provide to the aircraft?. What is the axis of flight that runs from the nose tip to the tail of the aircraft?. Describes what happens to an aircraft when the CG moves rearward.. When flaps are extended during takeoff, what do they provide to the aircraft?. Forms of Matter:. Solids: Rigid; retain their shape unless distorted by a force. Examples: rock, wood, plastic, iron….. Liquids: Flow readily; conform to the shape of the container; have a well defined boundary; have densities greater than gases. Examples: water, beverages, gasoline, blood….. 2. The denser the atmosphere…. the greater its weight, and . the greater its air pressure.. 3. atmospheric pressure -. . a.k.a. .; . barometric pressure or air pressure.. the pressure due to the weight of the overlying atmosphere.. What . are t. he . subcomponents of an . airplane? . What . is the basic structure of an . aircraft? . What is . designed to withstand all aerodynamic . forces. ?.

We have been studying the motion of regular-sized (. macroscopic. ) objects. We know these objects are made up of countless atoms and molecules (. Danielle . Hettmann. and Chris . Saleh. SYST460 – Fall 2011. Static temperature:. . measure of the temperature at the surface of the aircraft. Ambient temperature: . measure of the temperature of the air in the region surrounding the aircraft. Section 11.2 – Properties of the Atmosphere 8 th Grade Earth and Space Science Class Notes Temperature Temperature – measure of the average kinetic energy of the particles in a material Higher the temperature = faster particle movement Properties of the Atmosphere Heat vs. Temperature Temperature – measure of how rapidly or slowly molecules move around. Higher the temperature = faster particle movement Heat - is the transfer of energy that occurs because of a difference in temperature between substances John Huthnance. 1. , Mark Inall. 2. , Neil Fraser. 2. 1.
