How do particle motion and temperature change as a material absorbs heat?
Temperature is proportional to the average kinetic energy of the molecules of a gas substance, as a good example. Hence, when temperature rises, the molecules move faster, they hit the walls of containers more (hence raising pressure), which may increase the volume (depending on the container - eg. plastic container vs a balloon). If the volume is not able to be increased, the pressure remains at that level. PV=nRT P=pressure V=volume n=number of moles R=a constant T=temperature With the above equation, you can see that by decreasing T, either/both of pressure and/or volume must change so that the left side of the equation equals the right.
A phase diagram identifies the state of matter of a substance for specific combinations of?
Phase diagrams usually show phase transition boundaries relative to two variables. WHICH two variables depends on what they're trying to show, but usually is is two of the following: Temperature Pressure Volume/density Mole fraction Mass fraction ========== PT PV less commonly - TV Isobaric T vs mole fraction (e.g. melting point diagram) Isothermal P vs mole fraction (e.g. a vapor pressure diagram)
How is air pressure different from the top of the mountain vs the bottom of a mountain?
well a moutian if it is tall enough can reach the sky and air pressure their is 0
What does the slope of mass vs weight graph represent?
The slop of a line which represents mass over volume would give you density.
Fan vs blower what difference?
Fans, blowers and compressors are differentiated by the method used to move the air, and by the system pressure they must operate against. As per American Society of Mechanical Engineers (ASME) the specific ratio - the ratio of the discharge pressure over the suction pressure is used for defining the fans, blowers and compressors. Equipment /Specific Ratio /Pressure rise (mmWg) Fans /Up to 1.11 /1136 Blowers /1.11 to 1.20 /1136 2066 Compressors /more than 1.20 /
What is Evolutionary Trends Species Sorting?
Direct Development vs Indirect Development.
Direct cost vs indirect cost?
Direct cost is that cost which is directly attributable to units of product like raw material and labor while indirect cost is not directly attributable like factory maintenance cost.
Hepatic detoxification and excretion?
bilirubin (indirect vs. direct) and ammonia ....might just be overwhelmed from a hemolytic anemia....why getting a fractionated bilirubin is good....
Is the graph created by Pressure vs Volume an exponential graph when constant in temperature?
It depends, you have to know which variable (Temperature/Pressure/Volume) is constant, see here http://hypertextbook.com/physics/thermal/pressure-volume/
Is controlling variables a controlled experiment?
an experiment to test a scientific hypothesis in which the variable component is controlled, not random, eg In an experiment that measures volume vs time to boiling, the volume, being the indirect variable, is measured.
How do you graph mass vs volume?
Mass vs Volume graphs have a positive slope and and y intercept of approximately zero
What unit does a barograph measure in?
A barograph is a device that monitors pressure. It plots pressure vs time. Units can be kPa vs hr.
What is the formula for void ratio?
Volume of voids divided by Volume of solids
The relationship between the pressure and volume of gases is given by what law?
Boyle's Ideal Gas Law:p1.V1 = p2.V2 = constant when temperature and number of moles are kept invariable.
Why is the pressure on ground more when a men is walking than when a men is standing?
The difference is dynamic pressure vs. static pressure.
How do you calculate void ratio in concrete?
1) weight of cement in one cube divided by density of cement = volume of cement in a cube: 2) Similarly volume of fine & Coarse aggregate can be calculated 3) Adding all one will get volume of solids in a Cube-Vs: 4) Subtracting Vs from volume of cube Vc one would get volume of voids Vv 5) taking ratio of Vv to Vs one would get void ratio
What is the volume of a sphere if the radius is 17m?
In order to solve this we need to understand the formula needed to find Volume of a Sphere, here on abbreviated as Vs. Vs = (4/3)(Pi)(Radius3) Now we can begin the calculation process: Vs = (4/3)(3.14159265)(17 meters³) Vs = (4/3)(3.14159265)(4913 meters³) Vs = 20579.52625 meters³ So there it is, Vs = 20579.52625 meters³ when r = 17m.
