If the Titan lake froze, how would the change in kinetic energy affect the speed of the molecules found in the lake? (Choose two)
The kinetic energy would increase, the molecules would move faster.
The kinetic energy would decrease, the molecules would move slower.
There would be no change in kinetic energy. The molecules would move at the same speed.

codfish influenced the yankee trade because they traded it with the americans and the americans traded livestock, molasses and stuff that they can make clothes out of (like wool, and leather). they also could make weapons to.

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69
