An air bubble has a volume of 1.70 cm3 when it is released by a submarine 115 m below the surface of a lake. What is the volume of the bubble when it reaches the surface? Assume the temperature and the number of air molecules in the bubble remain constant during its ascent. ?cm3

1. People buying food in sealed bags at high elevation often notice that the bags are puffed up because the air inside has expanded. A bag of pretzels was packed at a pressure of 1.00 atm and a temperature of 22.0 C. When opened at a summer picnic in Santa Fe, New Mexico, at a temperature of 32.0 C, the volume of air in the bag is 1.13 times its original volume. What is the pressure of the air P Santa Fe? = 0.079 Santa Fe X atm

1. Suppose the amount of air in a person's lungs is 2.2 L, Calculate the number of moles of air molecules in the person’s lungs when the pressure there is atmospheric pressure. Note that the air is at 37.0°C (body temperature). 2.   An expensive vacuum system can achieve a pressure as low as 1.05 × 10-7 Pa at 20°C, How many atoms are there in a cubic centimeter at this pressure and temperature?

1. An expensive vacuum system can achieve a pressure as low as 1.83 ✕ 10−7 N/m2 at 26°C. How many atoms are there in a cubic centimeter at this pressure and temperature? 2. The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 4.80 g peanut if the energy from burning it is transferred to 0.600 kg of water held in a 0.130 kg aluminum cup, causing a 44.0°C temperature increase?
