lake, where the temperature and pressure are 8°C and 6.4 atm to the water’s surface where the temperature is 25°C and the pressure is 1.0 atm. Calculate the final volume (in m3) of the bubble if its initial volume was 2.1 cm3.

The tidal lung volume of human breathing, representing the amount of air inhaled and exhaled in a normal breath, is 500 cm³. (Assume atmospheric pressure.) (a) What is the number of molecules of air inhaled with each human breath when the air temperature is 25.0°C? molecules (b) If the molar mass of air is 28.96 g/mol, what is the mass (in g) of air molecules inhaled with each breath? (Assume the air temperature is 25.0°C.) g (c) It has been calculated that all of the air in Earth's atmosphere could be collected into a sphere of diameter 1,999 km at a pressure of 1.00 atm. What is the mass (in kg) of the air in Earth's atmosphere? (Assume the density of air used in this calculation was 1.225 kg/m³.) kg (d) If all 7 billion humans on Earth inhaled simultaneously, what percentage of the atmosphere would be inhaled during this process? (Assume the air temperature is 25.0°C everywhere on Earth.) %

What is the pressure of the gas in the cylinder, in kPa (kiloPascal)? h = 0.620 m, Pmercury = 13,600 kg/m3, 1.0 atm = 1.00 x 105 Pa = 100 kPa, and g = 10.0 m/s?. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Mercury. p = 13,600 kg/m² Pen

An ideal gas is in a room held at a constant temperature and the pressure set at 2 atmospheres (atm). The balloon’s initial volume is 40 cm3. If the pressure is increased to 8 atm, what is the new volume of the balloon?

A tank is filled with oil whose density is p-850 kg/m3. If the volume of the tank is V= 3m³, determine the amount of mass m in the tank.

A gas is held in a container with volume 516 cm3. If the pressure of the gas inside the container is 100 kPa, what is the pressure of the gas, in the unit of kPa, when it is expanded to 733 cm3? Assume that the temperature of the gas does not change.

An airplane passenger has a volume V1 of air in his stomach just before the plane takes off from a sea-level airport. a. What volume will this quantity of air have at cruising altitude at the same temperature (body temperature), in terms of V1, the pressure on the ground P1, and the cabin pressure at cruising altitude P2?  b. What is this volume, in cubic centimeters, if the initial volume is 95 cm3 and the cabin pressure drops to 7.50 × 104 Pa when the plane is at cruising altitude?
