Assume the population is normally distributed. given a sample size of 225, with sample mean of 750 and standard deviation of 30 we perform the following hypothesis test, H0: u=745 Ha:# 745 U

Temperature and kinetic energy are proportional. a) adirectly b) directly c) indirectly

What is the approximate vapor pressure when the gas condenses at 70 degrees celsius

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
