Question

the first part of the lab procedure focused on temperature. there were several factors, which are listed below. label each factor as \variable\ or \constant.\ amount of water: reaction rate: temperature: initial amount of tablet: particle size: done

Explanation:

In a lab procedure focused on temperature, we analyze each factor:

• Amount of water: In a controlled experiment (to study temperature's effect), the amount of water is kept constant to isolate temperature's impact. So it's a constant.
• Reaction rate: Reaction rate depends on temperature (the factor we're studying), so it changes as temperature changes. Thus, it's a variable.
• Temperature: Since the lab focuses on temperature, it's the independent variable we manipulate or observe changes in, so it's a variable.
• Initial amount of tablet: To control the experiment, the initial amount of the tablet is kept constant (unless it's a factor being studied, which it's not here as the focus is temperature). So it's a constant.
• Particle size: Similar to the above, particle size is kept constant in a temperature - focused experiment to ensure only temperature affects the reaction. So it's a constant.

Answer:

• Amount of water: Constant
• Reaction rate: Variable
• Temperature: Variable
• Initial amount of tablet: Constant
• Particle size: Constant
