Given figure represents pH, partial pressure of CO$_2$ (pCO$_2$), and temperature (T) in an experiment conducted in a water sample over 20 days. Which of the following statements can definitely be made based on this experiment?
The given figure shows the variation of partial pressure of CO2 (pCO2), pH, and temperature (T) over 20 days in a water sample. We need to analyze this data to determine which statement can definitely be made based on the experiment.
- Analyzing the graph for pCO2:
- pCO2 starts at a lower value and increases over the 20 days.
- Analyzing the graph for pH:
- pH starts high and decreases over the 20 days.
- Analyzing the graph for temperature (T):
- Temperature starts lower and increases over the 20 days.
Based on the analyzed data, we can conclude the following about the provided options:
- High CO2 causes global warming: While this statement is scientifically relevant, it is not directly supported or proven by the data from this specific experiment.
- High temperature causes acidification: While increased temperature can lead to acidification, this statement cannot be definitively concluded solely from the given graphs.
- There is a decrease in pH and an increase in both T and pCO2 over 20 days: This statement directly corresponds with the observed data from the graphs.
- pH and pCO2 are positively correlated while pH and T are inversely correlated: The graphs show a decrease in pH while both T and pCO2 increase, which suggests a negative correlation with pH for both factors rather than a positive one with pCO2.
Therefore, the statement that can definitely be made based on the experiment is:
There is a decrease in pH and an increase in both T and pCO2 over 20 days.
Important Questions from Data Interpetation (Notes)
- Answer the question on the basis of the informations given below :
Three different climatic factors for four cities in India are shown in the following table :City Average Annual Rainfall (in mm) Average Annual Temperature (in degree centigrade) Maximum humidity in the year A 75 21 126 B 86 17 130 C 68 17 160 D 70 24 150
If humidity factor is defined as average annual rainfall divided by average annual temperature for the cities, the humidity factor is highest for which city ?
