Question
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?
