Praxis II Middle School Science 5440 Latest Update Graded A+ "Zeroth" Law of Thermodynamics If systems 1 and 2 are both in equilibrium with 3, then 1 and 2 are also in equilibrium with each other. 1st Law of Thermodynamics Matter and energy are conserved (energy in = energy out) in a closed system. 2 elements - liquid at room temperature Hg, Br 2nd Law of Thermodynamics Entropy always increases in a closed system. Not all energy is transferred; some is "lost" as heat. 3r...

big bang - -still energy left from explosion -discovered in 1960s -assumes earth came from material -Kant created most pop model of formation (planet accretion) nebula - beginning form of planets many bump into others and combine earths composition - -more dense material in center -heterogeneous (bc heat and dense elements melt and flow) -accretion -compression -radioactive decay 3 layers of earth - -based on composition -core, mantle, crust -metallic core sank to center lithospher...

origin of earth - Answer-• Supernova: death of a star (great explosion) • Supernova happened 4.6 bya, dust and gas flattens to a disk and spins faster due to gravity and solar nebula formed. • Solar Nebula: describes formation of Earth 4.5 bya • Nebula: gas cloud origin of oceans - Answer-• volcanic explosion, H2O condensed and rained down for thousands of years to create oceans • icy comets hitting earth (responsible for 1/2 of earths ocean water) origin of life - Answer-•...

The Earth - origin of Earth, oceans, life; the Earth's internal layers... - origin of Earth, oceans, life; the Earth's internal layers... Origin of Earth, Oceans, Life: • Earth: Supernova (explosion of a star-4.6 bya)- earth (nebula made of gas and dust) was formed 4.5 billion years ago. • Oceans: Volcanic expulsion, rained for thousands of years then hit by icy comets; volcanic outgassing and ice from comets • Life: 3.7 billion years ago life was created- animals have been arou...

The lights on the outside of the canopy of an inflatable liferaft operate - Automatically when the raft is inflated While adrift in an inflatable liferaft in hot, tropical weather - Deflating the floor panels may help to cool personnel. When hoisting a boat on gravity type davits using an electric motor driven winch, the davit arms should be brought up - Until just before they make contact with the limit switch, and then hand cranked to their final position. What is the purpose of tricing...

seismic waves - Answer-Vibrations that travel through Earth carrying the energy released during an earthquake. crust - Answer-the outer layer of the Earth mantle - Answer-the layer of hot, solid material between Earth's crust and core lithosphere - Answer-the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle asthenosphere - Answer-the soft layer of the mantle on which the lithosphere floats basalt - Answer-a rock that makes up much of the o...

Earth's Structure - ANSWER-- Inner core is 6000°C made up of solid iron and nickel - Outer core liquid melted 2,000 Km thick - Mantle semi molten Asthenosphere - ANSWER-The upper semi molten part of mantle Lithosphere - ANSWER-The rigid mantle and crust Types of crust - ANSWER-- Continental- 30-70 km thick and less dense - Oceanic- 6-10 km thick and more dense Convection currents - ANSWER-- Lower parts of mantle rise as heated up, cool down become more dense and slowly sink - Circula...
