The air pressure inside a passenger tire is 228 kPa. What is this pressure in atmospheres?

Answer 1

The pressure is #2.26 Atm#

To convert the units of pressure as requested, let's apply the idea of conversion factors. First, we find the equivalent number of Pa that an atmosphere, or Atm, represents:

#1Atm = 1.01xx10^5Pa#

This may be expressed as a conversion factor as

#(1Atm) /(1.01xx10^5Pa)# or #(1.01xx10^5Pa)/(1Atm)#

We then choose the one that cancels the units we want to remove and keeps the ones we want, both of which are true.

#228color(red)cancel(kPa) (1000color(blue)cancel(Pa))/color(red)cancel(kPa)*(1Atm) /(1.01xx10^5color(blue)cancel(Pa)) =2.26 Atm#

Where we have also used the conversion factor for #Pa# to #kPa#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
