The volume of a gas is 300 mL at 740 torr and 25 degrees C. If the pressure remains constant and the temperature is raised to 100 degrees C, the new volume will be?
The volume of a sample of ideal gas at 27 °C is 342 mL. a. What will the volume of the gas become if the gas is heated at constant pressure to 52°C? Show your calculations. b. What will the volume of the gas become if instead it is cooled to -272°C? Show your calculations.
A sample of gas has a volume of 3.73 L at a temperature of 59.20 °C. The gas sample is cooled to a temperature of 8.64 °C (assume pressure and amount of gas are held constant). Predict whether the new volume is greater or less than the original volume, and calculate the new volume. New volume larger or smaller? New volume = L
1- A gas sample has a pressure of 1.17 bar. What is this pressure in atm? Hint: 1 atm = 101.3 kPa = 1.013 bar = 760 torr = 760 mm Hg = 14.7 psi 2- A sample of gas has a volume of 474 mL at a pressure of 3.49 atm. The gas is compressed and now has a pressure of 7.72 atm. Predict if the new volume is greater or less than the initial volume, and calculate the...
