If measurements of a gas are 75l and 300 kilo-pascals and then the gas is measured a second time and found to be 50l, describe what had to happen to the pressure (if temperature remained constant). include which law supports this observation.

The smokey mountains have over 2,100 miles of rushing mountain streams and rivers that flow through the park. in each mile lives a diverse community of native fish, amphibians, insects, and larvae, some of which are found only in the southern appalachians. park managers and scientific researchers test many factors such as fish populations, the watersheds and water tests to determine a) too many lizards are present b) the water quality of the stream c) rainwater is running into local streams d) if visitors to the park are overstaying their welcome
