What Celsius temperature, T2 , is required to change the volume of the gas sample in Part A (T1 = 8.0 °C Vi = 1.69x103 L ) to a volume of 3.38x103 L ? Assume no change in pressure or the amount of gas in the balloon. Express your answer with the appropriate units.

A room has dimensions of 7.2 m by 5.9 m by 3.2 m. The pressure inside the room is 90,000 Pa and the temperature is 37 degrees C. Another room with the same dimensions and pressure has a temperature of -7 degrees C. If air has a molar mass of 29 g/mol, calculate the mass of air in each room in kg. Which room has the larger mass of air? Answer in kg rounded to the nearest tenths place.

A cylindrical tank with a diameter of 1.0 m and a length of 3.0 m holds oxygen gas (O2) at a temperature of 18◦ C. If the pressure of the gas is 1.0 × 106 Pa, how many oxygen atoms are in the tank?

When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV4 =C where C is a constant. Suppose that at a certain instant the volume is 600 cubic centimeters and the pressure is 79 kPa and is decreasing at a rate of 14 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant? cm min (Pa stands for Pascal -- it is equivalent to one Newton/(meter squared); kPa is a kiloPascal or 1000 Pascals.

26.4 mol of gas at atmospheric pressure is compressed. What is the volume of the compressed gas in the unit of m3 when the gauge pressure of the compressed gas is 30.6 kPa and the temperature of the gas is 40°C? The atmospheric pressure is 101.3 kPa.

Rectangular tank contains 3.0 kg of air. The length of the tank is 1.1 m and the width is 0.9 m. The pressure p of the tank is 1.2 bar temperature T₁ is -20 °C. Calculate a) Amount of air n b) Height of the tank h c) Density of air p mol (with zero decimal accuracy) m (with one decimal accuracy) kg/m3 (with one decimal accuracy) If the temperature inside the tank increases by 50 °C, what is the new pressure in the tank? d) New pressure P2 bar (with one decimal accuracy)

A bicycle tire has a pressure of 6.95 × 105 Pa at a temperature of 16°C and contains 2.00 L of gas. a)What will its pressure be, in pascals, if you let out an amount of air that has a volume of 105 cm3 at atmospheric pressure and at the temperature of the tire? Assume tire temperature and volume remain constant.
