Jane walks the railroad tracks and notices that there are 1 cm gaps between the rails on the tracks. She wonders why the construction crews would leave these openings. Being an ace chemistry student who understands the Kinetic Theory, Jane immediately understands why. Follow her reasoning: Because Jane understands the kinetic theory of matter, she rationalizes that the individual iron atoms occupy a the same amount of space as they needed at the cooler temperature.
b less space than they needed at the cooler temperature
c more space than they needed at the cooler temperature

Suppose you have designed a new thermometer called the x thermometer. on the x scale the boiling point of water is 129 ? x and the freezing point of water is 13 ? x. part a at what temperature are the readings on the fahrenheit and x thermometers the same?

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
