QUESTION 12 At constant temperature, an ideal gas is at a pressure of 30 cm of mercury and a volume of 5L. If the pressure is increased to 60 cm of mercury, the new volume will be 5 L 10 L 2.5 L 25 L QUESTION 13

Gas is confined in a tank at a pressure of 9.2 atm and a temperature of 21.5°C. If two-thirds of the gas is withdrawn and the temperature is raised to 85.0°C, what is the pressure of the gas remaining in the tank? ?atm

A quantity of mercury occupies 400.0 cm³ at 0°C. What volume will it occupy when heated to 50°C? Mercury has a volume expansion coefficient of 180 x 10-6 K-1. 450 cm3 401.8 cm3 O403.6 cm³ O409.7 cm3

You happen to come across a piece of metal that has a density of p = 7.43 g/cm³ when the temperature is To = 45.0 °C. If the metal is cooled to a temperature of T = 0.00 °C, does the density change? No, because as the volume changes so does the mass. No, density does not depend on temperature. Yes, since the metal contracts and the mass is constant, the density will increase. Yes, the density will decrease since the volume changes. Calculate the density of the piece of metal at this temperature, p1. The coefficient of volume expansion for this piece of metal is ß = 8.43 x 10-s 1°°C.

The boiling point of a liquid is 28.3°C. A portion of the liquid is at equilibrium with its vapor at 22.3°C in a sealed flask. The temperature rises to to 32.6°C.What happens inside the container? Liquid is converted to vapor, the new equilbrium mixture contains less liquid and more vapor. The vapor is all converted to liquid. Vapor is converted to liquid, the new equilibrium mixture contains more liquid and less vapor. The liquid is all converted to vapor.

33. A bicycle tire has a pressure of 7.00 × 10° N/m² at a temperature of 18.0°C and contains 2.00 L of gas. What will its pressure be if you let out an amount of air that has a volume of 100 cm³ at atmospheric pressure? Assume tire temperature and volume remain constant.

If 23.5 moles of an ideal gas occupies 0.0465 cubic meters at 14.5 °C, what is the pressure of the gas? pressure: Pa

A container of gas holds 0.74 moles of neon gas. If the volume of the container is 11.8 liters and the pressure inside is 1.97 atm, what is the temperature (in K) of the gas?

Gas is confined in a tank at a pressure of 13.1 atm and a temperature of 28.0°C. If two-thirds of the gas is withdrawn and the temperature is raised to 89.0°C, what is the pressure of the gas remaining in the tank?

A gas under constant pressure has a volume of 30.57m^3 and a temperature of 59.0 K. A change in temperature caused the volume to change to 121.14m^3. Based on the relationship between volume and temperature, what must have happened to the temperature? A- Temperature decreased B- Temperature increased C- Temperature stayed the same D- Temperature trend can not be determined
