Yes, unless you mean 40oC. That is because the boiling point of pentane is 36.1oC (97oF). So above the boiling point temperature pentane would exist as a gas.
You would subtract 40 degrees from 180 degrees so it would look like this:180 degrees - 40 degrees = 140 degrees
It is 40 degrees
Not necessarily. When it is 40 degrees Celsius outside, it is sweltering!
In degree mode. cos(40) = 0.7660444431 degrees ( 77 degrees will do ) In radians. cos(40) = - 0.6669380617 radians

pentane and other alkanes above it
Liquid pentane does not conduct electricity because it has a net charge. This is as a result of the liquid not being an ion.
Pentane.
As pentane is boiled, the intermolecular bonds between molecules of pentane are broken. This makes pentane molecules free to move as they please and expand to fill any volume.
This is a really vague question, what type of liquid are you talking about?
As the number of carbon atom increases, compounds tend to be liquid (or even solid).
transfer pentene liquid
Pentane is liquid at room temperature the melting and boiling point are respectively -130C and 36C. SOLID -130C-LIQUID-36C-GAS (left to right is phase change alternated respectively by melting and boiling normal temperature)
somewhere around 56 degrees C
C5h12 + 8o2 --> 5co2 + 6h2o
Yes, basically. The density will change, but in the case of a liquid, the change is quite small, for most practical purposes.
(-40) degrees Fahrenheit = (-40) degrees Celsius.
