A 2.0L balloon at room temperature (20.0oC) is placed in a refrigerator at 3.0oC. What is the volume of the balloon after it cools in the refrigerator? What would be the final size of the balloon in the example problem above if it were placed in a -18oC freezer?

Infants born with severe respiratory problems are sometimes given liquid ventilation: they breathe a liquid that can dissolve more oxygen than air can hold. one of these liquids is a fluorinated compound, cf3(cf2)7br. the solubility of oxygen in this liquid is 66 mlo2 per 100 ml liquid. in contrast, air is 21 % oxygen by volume. calculate the moles of o2 present in an infant's lungs (volume: 12 ml ) if the infant takes a full breath of air. assume a pressure of 1 atm in the lungs.

During which time interval does the object travel approximately 10 meters

Which of these conditions most likely produces an unstable isotope?
