Question

question 1 (3 points) identify whether the following observations are qualitative or quantitative. the volume of the gas is 250 milliliters the metal is shiny and smooth the liquid is clear and colorless the temperature of the solution is 45°c the flower has a sweet fragrance the mass of the object is 150 grams 1. qualitative 2. quantitative

Explanation:

Quantitative observations are those that involve a number or measurement. Qualitative observations describe qualities or characteristics. The volume of gas (250 milliliters), temperature of solution ($45^{\circ}C$), and mass of object (150 grams) are numerical measurements. The shininess and smoothness of metal, clearness and color - lessness of liquid, and sweet fragrance of flower are descriptive qualities.

Answer:

1. The volume of the gas is 250 milliliters - Quantitative
2. The metal is shiny and smooth - Qualitative
3. The liquid is clear and colorless - Qualitative
4. The temperature of the solution is $45^{\circ}C$ - Quantitative
5. The flower has a sweet fragrance - Qualitative
6. The mass of the object is 150 grams - Quantitative
