Because most leaves have two sides, do you think you have to double your calculation to obtain the surface area of one leaf? why or why not?

     Let's imagine that a leave is like a triangle, so, with this, how do we do the math to know the area? It's pretty simple right? A= l^2/4

      With that, if you imagine a leave as a triangle, what you need to know is its height by measuring it, and then do the math to find the result. You don't have to double ta calculation because you're already using the entire surface area by the height.

answer; ///i believe that the correct answer is (e); check first good

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.
