Achemist notices some silvery liquid on the floor in her lab. she wonders if someone accidentally broke a mercury thermometer, but did not thoroughly clean up the mess. she decides to find out of the silver stuff is really mercury. from her tests with the substance, she finds out that the melting point for the liquid is 275 k. a reference book says that the melting point for mercury is -38.87°c. is this substance mercury? explain your answer and show all relevant calculations.

Use the library or internet to research each planet. make a chart comparing the following: approximate surface temperature relative surface gravity compared to earth atmospheric gases water in any form: solid, gas, or liquid when you have completed your chart, use the information you have collected to answer the following questions: which is the hottest planet? which is the coldest planet? which planet's temperature is closest to that of earth? (note: water boils at 100°c/212°f. water freezes at 0°c/32°f) which planet has the greatest gravitational attraction? which planet has the least gravitational attraction? which planet's gravitational pull is closest to that of earth? do any of the planets have oxygen in their atmosphere? which planet's atmosphere most resembles that of earth? do any of the planets have flowing water? which planet's water resources (solid, gas, or liquid) might be close to the amount on earth? which planet most resembles earth in terms of all of the factors: temperature, gravity, atmosphere, and water? if earth became an uninhabitable planet, which planet do you think would be the next best to live on? explain your answer.
