To test the first hypothesis, you measured the reaction rate for several different volumes.✔ temperatures.densities.particle sizes.
The data showed that for higher temperatures, the reaction rate ✔ increases.decreases.does not change.fluctuates randomly.
To test the second hypothesis, you measured the reaction rate for several different volumes.temperatures.densities.✔ particle sizes.
The data showed that for smaller particle sizes, the reaction rate ✔ increases.decreases.does not change.fluctuates randomly.

The longer the reaction time is, the ✔ lessergreaterthe reaction rate is. Reaction time is
proportional✔ inversely proportionalequal to reaction rate.
Question text not available
The smaller the particle size, the lesser✔ greaterthe surface area. Therefore, particle size is
proportional✔ inversely proportionalequal to surface area.

Suppose that a student did not stop the timer as soon as bubbling stopped during a test at 40°C. Check all possible resulting errors.
Suppose that a different student obtained reaction rates for the particle-size experiment, and that these rates did not show a pattern. Check all possible sources of this error.
Reptiles, amphibians, and fish are all cold-blooded animals. Their body temperatures are determined by their surroundings. How does a cold-blooded animal’s ability to digest food change in colder temperatures?
