Answer:
The answer is Diffusion.
Explanation:
Diffusion is a movement of molecules(substances) from a region of high concentration to a region of low concentration down a concentration gradient.
Answer:
Part 1: W = 116 Y = 163
Part 2: Since 232 is the mailing point of 2 kg then you would divide 232 by 2 to get the melting point for 1 kg, the same with Y.
Known :
r = 6 in
h = 11 in
Asked :
Volume = ...?
Answer :
V = πr²h
= 3.14 × 6² × 11
= 3.14 × 36 × 11
= 3.14 × 396
= <u>1</u><u>,</u><u>2</u><u>4</u><u>3</u><u>.</u><u>4</u><u>4</u><u> </u><u>in³</u>
So, the volume is 1,243.44 in³ (2nd choice)
