Calculating the Effect of Temperature Changes on Pressure
The gas pressure in an aerosol can is 1.5 atm at 25 °C. Assuming that the gas obeys the ideal-gas equation, what is the pressure when the can is heated to 450 °C?
The pressure in a natural-gas tank is maintained at 2.20 atm. On a day when the temperature is -15 °C, the volume of gas in the tank is 3.25 × 103 m3. What is the volume of the same quantity of gas on a day when the temperature is 31 °C?
Cardiovascular Adaptations of the Heart We have four chambers of the heart and they are four different pumping systems o Remember that the right side is on the left side of your paper. o 1 pump comes from the right atrium to the right ventricle then out through the pulmonary artery and into lungs (to get oxygen). Then it will return to the heart through the pulmonary vein and enter the left atria, then the left ventricle. Then it will leave the heart through the aorta and go through the body to distribute oxygen. When blood enters the right side of the heart, it is depleted of oxygen. o The left and right side of the heart are separa
