A gas is in a container that is able to expand or contract so the pressure inside the container stays constant. The gas is steadily heated from 20 to 40 degrees Celsius. What is the percent change in the volume of the container? Governing Equation: Percent change in volume: Assumptions:

! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Consider helium at 350 K and 0.75 m³/kg. Use dP = ()¸dT + (P),dv for calculations. The gas constant of helium is R= 2.0769 kPa-m³ /kg.K. Determine the change in pressure corresponding to an increase of 4 percent in specific volume at constant temperature. (You must provide an answer before moving on to the next part.) The change in pressure corresponding to an increase of 4 percent in specific volume at constant temperature is - kPa.

Q2:- Note: 1 Torr = 0.133 kPa & 1 atm 101.325 kPa (A) A spray metal bottle is used for polishing some Aluminum samples until it is empty. Then, the rest propellant gas inside the bottle has a pressure of 1344 torr at 23 °C. Finally, if the spray bottle is thrown into a fire at a temperature equals 475 °C. Determine the pressure in the hot bottle in kPa? Assuming no change in volume.
