It results change only in it's kinetic energy, it's KE will increase in accord with the work-energy theorem
The liquid that will evaporate the quickest would be water.
<em>~The rest are mixtures, and have more ingrediants in them, therefore the answer should be water. (in which it has no other ingrediants in it but water itself)</em>

Answer:
t = 8.45 sec
car distance d = 132.09 m
bike distance d = 157.08 m
Explanation:
GIVEN :
motorcycle is 25 m behind the car , therefore distance need to covered by bike to overtake car is 25+ d, when car reache distance d at time t
for car
by equation of motion
![d = ut + \frac{1}{2}at^2](https://tex.z-dn.net/?f=d%20%20%3D%20ut%20%2B%20%5Cfrac%7B1%7D%7B2%7Dat%5E2)
u = 0 starting from rest
![d = \frac{1}{2}at^2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7Dat%5E2)
![t^2 = \frac{2d}{a}](https://tex.z-dn.net/?f=t%5E2%20%3D%20%5Cfrac%7B2d%7D%7Ba%7D)
for bike
![d+25 = 0 + \frac{1}{2}*4.40t^2](https://tex.z-dn.net/?f=d%2B25%20%3D%200%20%2B%20%5Cfrac%7B1%7D%7B2%7D%2A4.40t%5E2)
![t^2= \frac{d+25}{2.20}](https://tex.z-dn.net/?f=t%5E2%3D%20%5Cfrac%7Bd%2B25%7D%7B2.20%7D)
equating time of both
![\frac{2d}{a} = \frac{d+25}{2.20}](https://tex.z-dn.net/?f=%5Cfrac%7B2d%7D%7Ba%7D%20%3D%20%5Cfrac%7Bd%2B25%7D%7B2.20%7D)
solving for d we get
d = 132 m
therefore t is![= \sqrt{\frac{2d}{a}}](https://tex.z-dn.net/?f=%20%3D%20%5Csqrt%7B%5Cfrac%7B2d%7D%7Ba%7D%7D)
![t = \sqrt{\frac{2*132}{3.70}}](https://tex.z-dn.net/?f=t%20%3D%20%20%5Csqrt%7B%5Cfrac%7B2%2A132%7D%7B3.70%7D%7D)
t = 8.45 sec
each travelled in time 8.45 sec as
for car
![d = \frac{1}{2}*3.70 *8.45^2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A3.70%20%2A8.45%5E2)
d = 132.09 m
fro bike
![d = \frac{1}{2}*4.40 *8.45^2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A4.40%20%2A8.45%5E2)
d = 157.08 m
