rearrange the ideal gas equation, PV=nRT to the form y=mx+b for the case where V is plotted on the y-axis and n on the x-axis. Name the equation, slope,a dn intercept - Answer- V= RT/P (n) slope: RT/P intercept: none Interpolation - Answer- estimating a value within the range of measured data extrapolation - Answer- projection; conjecture; V. extrapolate: infer (unknown information) from known information best fit line equation commonly takes y=mx+b format. What are your y, x, and...

Precipitation - ANSWER-the input to our hydrologic cycle lapse rates - ANSWER-Rates at which air cools and warms. Ideal Gas Law - ANSWER-PV=nRT; predicts that air temp drops at high elevations because air pressure is lower cold air: - ANSWER-holds less water vapor than warm air saturation vapor pressure - ANSWER-Maximum amount of water air will hold (warm air hold more water than cold air) saturated vapor pressure = actual vapor pressure at - ANSWER-15 degrees C General Atmosph...

Massachusetts Institute of Technology 5.112-Principles of Chemical Science Lecture 13-Kinetic Theory of Gases

The file discusses the relationship between the volume, temperature, and pressure of a gas. It explains how changes in volume and temperature affect the collision frequency of gas particles with the container wall, and how these changes influence the pressure of the gas. Additionally, it highlights the direct and inverse proportional relationships between volume and pressure, as well as temperature and pressure, and mentions that a graph of gas temperature plotted against pressure results in a s...

The branch which deals with the movement of energy from one form to the other and the relation between heat and temperature with energy and work done is called as thermodynamics. In other terms we can define thermodynamics as the science stream that deals with the study of the combined effects of heat and work on the changes of state of matter confined by the laws of thermodynamics.
