Passage
A solute is any substance that is dissolved in another substance, which is called the solvent.
A student tested the solubility (a measure of how much solute will dissolve into the solvent) of six different substances. The solubility of a substance at a given temperature is deﬁned as the concentration of the dissolved solute that is in equilibrium with the solvent.
Table 1 represents the concentration of dissolved substances in 100 grams of water at various temperatures.
The concentrations are expressed in grams of solute per 100 grams of water.

Q. According to Table 1, the concentrations of which of the following substances varies the least with temperature?

a)
HCl
b)
NH₃
c)
NaCl
d)
KCl

Correct answer is option 'C'. Can you explain this answer?

The best answer is C. The question asks you to look at the overall trends of the data sets for each substance. A good way to measure the degree to which data varies would be to ﬁnd the range, meaning subtract the lowest value from the highest value for each individual substance. In this problem it is clear that NaCl varies the least with temperature.

Directions:Read the passages and choose the best answer to each question.PassageSeveral scientists considered some different environmental factors and their inﬂuence on the growth of certain bacteria. The following experiments used Salmonella bacteria to measure the effect of pH levels, nutrients, and temperature on the number of bacteria produced within a given time period.Experiment 1A known quantity of Salmonella bacteria was placed in each of 3 Petri dishes with the same nutrient concentration at the same temperature. The pH level of each nutrient concentration in each dish was varied according to Table 1. On the pH scale, 7 represents neutral, values less than 7 indicate an acid, and values greater than 7 indicate a base. The lids of the Petri dishes were replaced after the bacteria were added and the dishes were left alone. After 6 hours, the percent growth of Salmonella bacteria was recorded (Table 1).Experiment 2A known quantity of Salmonella bacteria was placed in each of 3 Petri dishes with different nutrient concentrations in the form of organic compounds. The temperature and pH level (neutral 7) were held constant in each sample.The lids of the Petri dishes were replaced after the bacteria were added and the dishes were left alone. After 6 hours, the percent growth of Salmonella bacteria was recorded (Table 2).Experiment 3A known quantity of Salmonella bacteria was placed in each of 3 Petri dishes at different temperatures. The pH level and nutrient concentrations were held constant. The lids of the Petri dishes were replaced after the bacteria were added and the dishes were left alone. After 6 hours, the percent growth of Salmonella bacteria was recorded (Table 3).Q.Bacteria will generally reproduce until all of the nutrients available have been depleted. How could the experiment be altered to maximize the length of time that bacteria will reproduce?
