The table shows four samples of carbon dioxide and the temperature of the water that they were dissolved in. Which of the samples most likely had the lowest solubility? I know the answer is sample one (78) but i can't find the right words to explain my answer.

Sample one, with a temperature of 78 degrees, likely has the lowest solubility of carbon dioxide, as lower temperatures generally favor increased gas solubility in liquids according to Henry's Law.

The solubility of gases in liquids, such as carbon dioxide (CO₂) in water, tends to decrease with increasing temperature. This phenomenon is attributed to the principles of thermodynamics, specifically Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid and inversely proportional to the temperature.

In the given table, the temperature values are provided alongside each sample of dissolved carbon dioxide. Notably, as the temperature increases, the solubility of CO₂ generally decreases. Therefore, the sample with the lowest temperature, sample one at 78 degrees, is likely to exhibit the highest solubility of carbon dioxide compared to the other samples. This is because lower temperatures favor increased gas solubility in liquids.

In summary, according to Henry's Law, the solubility of carbon dioxide decreases with rising temperatures. Hence, sample one with the lowest temperature (78 degrees) likely has the highest solubility among the provided samples.

Answer:

Sample 1 = 78°

Step-by-step explanation:

As per the question, while testing the solubility of a solution comprising of water and carbon dioxide, sample 1 is likely to have the lowest solubility with the temperature of the water being 78°, the maximum. The reason for this result is that the 'solubility of carbon dioxide in the water' falls with an increase in the temperature due to the increase in kinetic energy which will enhance the motion between the molecules and allow them to escape.' Thus, the water with maximum temperature will have the lowest solubility. Hence, sample 1 is the correct answer.
