A weather balloon full of helium with a volume of 47.1 Lat
22°C is sitting inside an aircraft hangar. The temperature of
the hangar increases to 33°C. Which equation would be
easiest to use to find the new volume of the balloon?
A. PV = nRT
B. P1V1 = P2V2
C. (V1/T1) = (V2/T2)
D. P = (F/A)

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
