I was just wondering if anyone would be able to give out some interesting facts on clean technology (ie solar power, wind power, etc). It's for a speech I have to give at a local college, so any facts would be greatly appreciated. :)
Google those terms. You will gat many facts to use.
On a day with an air temperature of 75°F, you read the psychrometer and determine the relative humidity to be 74%. A sudden weather change (that does not affect the actual moisture content of the air) reduces the relative humidity to 70%. What was the temperature change?
