Answer the question based on the following text.  Question:   Ian sees an object with many colliding particles, and he compares it to another object with few colliding particles. Which is true about the objects the object with many colliding particles has a lower concentration of particles or the object with many colliding particles has a higher concentration of particles?    Text:  At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react.
the object with many colliding particles has a higher concentration of particles
Q: Answer the question based on the following text.  Question:   Fewer particles are deposited when a river's speed increases or decreases?    Text:  The size of the eroded particles depends on the velocity of the water. Eventually, the water deposits the materials. As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited.
A: increases
Question: Answer the question based on the following text.  Question:   Mike wants his circuits to be able to have a higher resistance, so that the current decreases. In order to do this, he will consider his resistors and increase them or decrease them?    Text:  We also saw that adding resistors to a series circuit increases the total resistance of the circuit, causing the current to decrease.
Answer: increase them
