I have a
blue liquid with density 1040 +- 20
yellow liquid 1190 +- 60,
(dark)red liquid 1170 +- 30
pink/light red liquid 1100 +- 60
my task is to find out what liquids are they
all of the densities were calculated in class(we were doing an experiment).
To identify the liquids based on their densities, you can compare the recorded densities with known densities of common liquids. Here is a step-by-step explanation on how to approach this problem:
1. Prepare a list of common liquids and their corresponding densities. Some examples include water (density of 1000 kg/m³), ethanol (density of 789 kg/m³), and oil (density of 900-950 kg/m³).
2. Calculate the range of acceptable densities for each liquid by subtracting and adding the given uncertainties to the recorded densities. For example:
- Blue liquid: 1040 - 20 = 1020 kg/m³ and 1040 + 20 = 1060 kg/m³
- Yellow liquid: 1190 - 60 = 1130 kg/m³ and 1190 + 60 = 1250 kg/m³
- Red liquid: 1170 - 30 = 1140 kg/m³ and 1170 + 30 = 1200 kg/m³
- Pink/light red liquid: 1100 - 60 = 1040 kg/m³ and 1100 + 60 = 1160 kg/m³
3. Compare the calculated acceptable density ranges with the known densities of common liquids. Identify the liquids that fall within these ranges.
For example, based on the acceptable density ranges, we can make the following matches:
- Blue liquid (1020-1060 kg/m³): Potentially water (density of 1000 kg/m³).
- Yellow liquid (1130-1250 kg/m³): There is no exact match, but it could be a mixture or a less common liquid.
- Red liquid (1140-1200 kg/m³): There is no exact match, but it could be a mixture or a less common liquid.
- Pink/light red liquid (1040-1160 kg/m³): Potentially ethanol (density of 789 kg/m³).
Note: The results above are just potential matches based on known densities. It's important to consider that there could be additional factors influencing the densities (e.g., impurities, temperature, etc.), so further investigation or confirmation may be required.
