It’s number two! please show step. thank you! **Problems:**1. A typical barometric pressure in Denver, Colorado, is 615 mm Hg. What is this pressure in atmospheres and kilopascals?2. The pressure of a sample of gas is measured at sea level with an open-end mercury manometer. Assuming atmospheric pressure is 760 mm Hg, determine the pressure of the gas in: (a) mm Hg (b) atm (c) kPa **Diagram Explanation:** - The diagram shows an open-end mercury manometer connected to a gas sample. The manometer is U-shaped, with one end open to the atmosphere. - The difference in the mercury levels in the U-shaped tube is marked as 26.4 cm.3. Sometimes leaving a bicycle in the sun on a hot day will cause a blowout. Why?4. A spray can is used until it is empty except for the propellant gas, which has a pressure of 1344 torr at 23 °C. If the can is thrown into a fire (T = 475 °C), what will be the pressure in the hot can?

There are many units of pressure. Some of the common units of pressure are atm, pascal, bar etc. Pressure of the atmosphere is 760 mm Hg.a. Pressure of the gas is equal to the sum of pressure in the atmosphere and the pressure due to the given height. Height of mercury in the manometer is 26.4 cm or 264 mm. The pressure of the gas is 264 mm Hg+760 mm Hg= 1024 mm Hg. b. One mm Hg is equal to 1/760 atm. Convert the temperature from mm Hg to atm. Pressure of gas= 1024 mm Hg1 atm760 mm Hg=1.35 atm Therefore, pressure of the gas is 1.35 atm.c. One mm Hg is equal to 0.133 kPa. Convert the temperature from mm Hg to kPa. Pressure of gas= 1024 mm Hg0.133 kPa1 mm Hg=136.19 kPa Therefore, pressure of the gas is 136.19 kPa.
