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.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
