Answer the following question given this paragraph: They will all blend together. The dyes will move through the water until an even distribution is achieved. The process of moving from areas of high amounts to areas of low amounts is called diffusion. Q: The process of moving from areas of high amounts to areas of low amounts is called what? A:
****
A: diffusion

Answer the following question given this paragraph: The reaction is exothermic and thus the sign of the enthalpy change is negative. Q: What enthalpy change is observed in an exothermic reaction? A:
OPTIONS:
- positive
- no change
- entropy
- negative
negative

Answer: blood vessels

Question: Answer the following question given this paragraph: Metal exposed to the outside elements will usually corrode if not protected. The corrosion process is a series of redox reactions involving the metal of the sculpture. In some situations, the metals are deliberately left unprotected so that the surface will undergo changes that may enhance the esthetic value of the work. Q: What process typically occurs to metal exposed to outside elements? A:
OPTIONS:
- shrinkage
- extraction
- explosion
- corrosion
Answer: corrosion

input: OPTIONS:
- melting point
- transformation point
- vapor point
