Agas sample is heated from -20.0°c to 57.0°c and the volume is increased from 2.00 l to 4.50 l. if the initial pressure is 0.140 atm, what is the final pressure

0.0812 atm

Explanation: The final pressure can be found using the combined gas law , where is 0.140 atm, is 2.00L, is , is 4.50L, and . By plugging in all these values into the combined gas law equation: , is found to be 0.08115942 atm, which can be rounded to 0.812 atm with 3 significant figures.

a graduated cylinder.

explanation:

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
