Question

Variables being held constant:**

- a. Candle type, water temperature, and room humidity.
- b. Candle height, container size, and water volume.
- c. Candle material, container shape, and atmospheric pressure.
- d. Candle color, water purity, and room temperature.

**Variables changing:**
- a. Water level and candle burning time.
- b. Water displacement and candle wax melting rate.
- c. Candle height and water color change.
- d. Water temperature and candle weight loss.

Answer 1

This question is about variables being held constant and variables that are changing in an experiment. Controlling these variables allows scientists to conduct controlled experiments to study the effects of specific factors on the outcome.

Step-by-step explanation:

In this question, the variables that are being held constant and the variables that are changing are listed. The variables being held constant are important factors that are not being altered in the experiment. The variables that are changing, on the other hand, are the ones being manipulated in the experiment. By controlling the variables that are being held constant and changing the variables that are being manipulated, scientists can conduct controlled experiments to study the effects of specific factors on the outcome of the experiment.
