Answer:
Step-by-step explanation:
Manipulated variables, also known as independent variables, are the factors or conditions that researchers intentionally change or manipulate in an experiment. Here are five examples of manipulated variables:
1. Temperature: Researchers can manipulate the temperature to examine its effect on various phenomena or systems. For example, they might study how temperature affects the growth of plants or the reaction rates of chemical reactions.
2. Time: Researchers can manipulate time by varying the duration of an experiment or changing the timing of events. This allows them to investigate the temporal aspects of a phenomenon or observe how changes over time impact the outcome.
3. Concentration: Concentration is another variable that researchers often manipulate in experiments. They can alter the concentration of a substance, such as a chemical solution, to study its impact on reaction rates, solubility, or other related processes.
4. Light intensity: Light intensity is a manipulated variable commonly used in studies related to photosynthesis, plant growth, or light-dependent reactions. Researchers can adjust the intensity of light to examine its influence on these biological processes.
5. Pressure: Manipulating pressure allows researchers to investigate its effects on gases, fluids, and various systems. For instance, they might examine how changing pressure affects the behavior of gases or the solubility of substances.
These are just a few examples of manipulated variables. In any experiment, the choice of manipulated variables depends on the specific research question and the phenomena under investigation.
