A plastic bottle is closed outdoors on a cold day when the temperature is -11.0°C and...
0.75 L bottle is cleaned, dried, and closed in a room where the air is 24°C and 38% relative humidity (that is, the water vapor in the air is 0.38 of the equilibrium vapor pressure at 24°C). The bottle is brought outside and stored at 0.0°C. (a) What mass of water condenses inside the bottle? (b) Would water condense at 10°C?
Question 28 (2 points) A balloon is inflated outdoors on a cold day in North Dakota at a temperature of -25°C to a volume of 2.5 L. The pressure remains constant. What is the volume of the balloon indoors at a temperature of 28°C? Show your calculation
On a cold rainy day where it was -12°C, a nitrogen-filled bike tire placed outdoors has the pressure of 5.44 atm. The tire volume was 6.7 L.You then take the bike indoors where the temperature was 25 °C. Assuming the volume of the bike tire does not change and no leaking occurred, answer the following two questions: 1. What is the pressure of the bike tire now? 2. How many moles of nitrogen gas does the tire contain?
Consider a “cold” winter day in with an air temperature of 7.22 °C and relative humidity of about 20% (moisture content 0.001 g H2O/g dry air). A person waiting at a bus stop inhales at an average rate of 8 g dry air/min and exhales air saturated with water at body temperature (37°C) and 1 atm (molal humidity is 6.7%). The heat capacity of dry air is 1.05 J/g- °C. Estimate the rate of heat loss from breathing. Express your...
On a particular summer day, the temperature is 30.0°C and the relative humidity is 77.0% (which means that the partial pressure of water vapor in the ambient air is 77.0% of the equilibrium vapor pressure of water). A sample of this air is placed in a 1.00 L flask, which is then closed and cooled to 5.00'C. A: 30.0°C, the vapor pressure of water is 31.8 mmHg. and at 5.00°C is 6.50 mmHg. What is the mass (in grams) of...
Part A A gas sample enclosed in a rigid metal container at room temperature (20.0∘C) has an absolute pressure p1. The container is immersed in hot water until it warms to 40.0∘C. What is the new absolute pressure p2? Express your answer in terms of p1. p2 = 1.0682p1 Part B Nitrogen gas is introduced into a large deflated plastic bag. No gas is allowed to escape, but as more and more nitrogen is added, the bag inflates to accommodate...
Be sure to answer all parts. On a humid day in New Orleans, the temperature is 23.0°C, and the partial pressure of water vapor in the air is 39.0 torr. The 9,000-ton air-conditioning system in the Louisiana Superdome maintains the inside air temperature at the same 23.0°C, but produces a partial pressure of water vapor of 10.0 torr. The volume of air in the dome is 2.4 x 106 m, and the total pressure inside and outside the dome are...
3) A weather balloon contains 12.0 m2 of hydrogen gas when the balloon is released from a location at which the temperature is 22.0°C and the ambient air pressure is 101 kPa. The balloon rises to a higher altitude where the temperature is -30.0°C and the ambient air pressure is 20.0 kPa. If the balloon is free to expand so that the pressure of the gas inside is equal to the ambient pressure outside, what is the new volume of the...
Worksheet 8 (Intro) 8. A metal tank contains three gases: oxygen, helium, and nitrogen. If the partial pressures of the three gases the tank are 35 atm of O, 5.0 atm of N2, and 25 atm of He, what is the total pressure inside of the tank? 9. The partial pressure of oxygen gas in a mixture of oxygen and nitrogen gases is 1.02 atm. The total pressure of the mixture is 2.43 atm. Calculate the partial pressure of nitrogen...
