Europe saw a rise in the middle class during the 17th and 18th centuries. which members of the middle class gained power and wealth during this time?

land owners

i don't know that i agree with that but what's the question ?

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
