Question

the second part of the lab procedure focused on particle size and also involved several factors. label each factor listed below as \variable\ or \constant.\ amount of water: reaction rate: temperature: initial amount of tablet: particle size: done

Explanation:

In a lab experiment focusing on particle size's effect, we analyze each factor:

• Amount of water: To isolate particle size's effect, water amount is kept fixed (constant).
• Reaction rate: Depends on other factors (like particle size), so it changes (variable).
• Temperature: Held constant to control variables (unless part of the experiment, but here particle size is the focus, so constant).
• Initial amount of tablet: Kept constant to ensure only particle size varies.
• Particle size: The independent variable being tested, so it changes (variable).

Answer:

• Amount of water: constant
• Reaction rate: variable
• Temperature: constant
• Initial amount of tablet: constant
• Particle size: variable
