Using Gay-Lussac's Law, calculate what the new pressure in the following situation. A tank of acetylene sits on the back of a truck. During the afternoon, the temperature
of a gas has reached 38°C (311 K) with a pressure of 508 kPa. That night, the
temperature drops to 29°C (302 K). Since the gas was in a metal tank, the volume
remained constant. What is the new pressure?
311 kPa
500 kPa
503 kPa
a
308 kPa
493 kPa

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

i'm pretty sure its b i might be wrong though!
