5. Juan's car gets an average of 24 miles per gallon of gas. How far can Juan go on
shtirl [24]

Claim:  Earth's atmospheric CO2 levels were measured over the past 1000 years and correlated with average world temperatures.  The data demostrate that Earth's temperature did not change during the period CO2 levels were steady.  But the past 100 years show a dramatic rise in CO2 levels, with a corresponding rise in world temperatures.  The CO2 rise can be traced back to the start of the industrial revolution, when machines began doing much of the work.  These machine burn fossil fuels and the increased CO2 levels have led to a dramatic rise in world temperatures.  The data clearly show the importance of reducing fossil fuel useage, as well as other CO2 emitters.  A world of incresing temperatures will lead to greater natural disasters, such as storms, flooding, hurricanes, and drought - all of which upset the ecological balance of the planet.

How long would it take for 1.50 mol of water at 100.0 âc to be converted completely into steam if heat were added at a constant
defon
To convert boiling water to steam, that would involve heat of vaporization. The heat of vaporization for water at atmospheric conditions is: ΔHvap = <span>2260 J/g.

Molar mass of water = 18 g/mol

Q = m</span>ΔHvap = (1.50 mol water)(18 g/mol)(<span>2260 J/g) = 61,020 J

Time = Q/Rate = (61,020 J)(1 s/20 J) = 3051 seconds

In order to express the answer in three significant units, let's convert that to minutes.
Time = 3051 s * 1min/30 s = <em>102 min</em></span>
