Divers get "the bends" come up too fast because the gas in their blood expands, forming bubbles in their blood. If a diver has 0.79 L of gas in her blood under a pressure of 155 atm, then rises instantaneously to a depth where her blood has a pressure of 70.0 atm, what will the volume of gas in her blood be?

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)

Who discovered a pattern to the elements in 1869?

Which of the following describes qualitative data? a) recording the temperature of a solid as it is warmed. b) noting the color of a solution as it is heated. c) measuring the volume of an object by water displacement. d) taking the mass of an object using a balance.
