. Rubbing alcohol has a boiling point of 108°C. What happens to the alcohol molecules at this temperature? A. They disappear.

B. They form a rigid, solid structure.

C. They begin to move closer to one another.

D. They begin to move independently from each other.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
