Answer 1

See the details.

Explanation:

QUALITATIVE OBSERVATIONS:

• They are variable.
• They are not accurate.
• They are not measurable.
• They cannot be recorded in terms of numbers.

Examples

• The freezing point of water is colder than its boiling point.
• A liter of ethanol is lighter than a liter of water.

QUANTITATIVE OBSERVATIONS:

• They are invariable.
• They are accurate.
• They are measurable.
• They can be recorded in terms of numbers.

Examples:

• The freezing point of water is `0^@"C"` and its boiling point is `100^@"C"`
• A liter of ethanol weighs approx. `"789 g"` and a liter of water weighs approx. `"1000 g"`
