Aryan conducted an experiment to study
the solubility of sugar in water under different sets of conditions as given in the table.
| Setup | Volume of water (mL) |
Sugar | Temperature (°C) |
|---|---|---|---|
| 1. | 50 | 10 g sugar crystals |
30 |
| 2. | 50 | 10 g finely powdered sugar |
60 |
| 3. | 100 | 10 g sugar crystals |
30 |
| 4. | 100 | 10 g finely powdered sugar |
60 |
Study the given data carefully and fill in the blanks by selecting an appropriate option.
Sugar will dissolve fastest in set-up __(i)__ and slowest in set-up __(ii)__.
This is because, solubility of sugar in water increases with ___(iii)__ in temperature, __(iv)__ in particle size of sugar and __(v)__ in volume of water.
| (i) | (ii) | (iii) | (iv) | (v) | |
|---|---|---|---|---|---|
| A | 4 | 1 | decrease | increase | decrease |
| B | 2 | 3 | increase | decrease | increase |
| C | 4 | 1 | increase | decrease | increase |
| D | 1 | 4 | increase | decrease | increase |
