Answer :
1) Luster → the shininess of a material
2) Freezing point → temperature at which a liquid becomes a solid
3) Viscosity → the measure of a substance's resistance to flow
4) Solubility → ability to dissolve in another substance
5) Ductility → able to be pulled into a wire
Explanation :
Luster : It is defined as the material which has the shining property.
Freezing point : It is the temperature at which the phase changes from liquid state to solid state at low temperature.
Viscosity : It measures the resistance of the liquids to flow .
Solubility : It is defined as the ability of a substance (solute) to dissolve into a liquid (solvent).
Ductility : It is defined as the ability of a metal into a thin wire without breaking.
The physical properties are correctly matched as: Luster corresponds to the shininess of a material, freezing point is the temperature at which a liquid becomes solid, viscosity is the measure of a substance's resistance to flow, solubility is the ability to dissolve in another substance, and ductility refers to a substance's ability to be pulled into a wire
The correct matches for the physical properties and their descriptions are as follows:
It's crucial to understand these properties in chemistry, as they help us identify and characterize different substances.

B. Fluorescent lamps operate at a higher temperature than incandescent lamps.
C. Fluorescent lamps dissipate more energy as light instead of heat than incandescent lamps.
D. Fluorescent lamps produce light with less glare than incandescent lamps.
Answer;
B. Fluorescent lamps operate at a higher temperature than incandescent lamps.
Explanation;
-A fluorescent lamp, is a type of electric light (lamp) that uses ultraviolet emitted by mercury vapor to excite a phosphor, which emits visible light.
-A fluorescent lamp produces less heat, thus, it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs.
-Fluorescent lamps operate best around room temperature. At much lower or higher temperatures, efficacy decreases.
B. Diamonds form in kimberlites under very high pressure.
C. Diamonds form in talc under very high pressure.
D. Diamonds form in talc under very low pressure.

It was correct on my quiz
Answer:
All of the above
Explanation:
According to Newton's second law of motion,
If a certain force is applied on objects of different mass, the lighter object will travel farther and faster. All the options in the question have pairs where one object is lighter than other.
So, Jim can throw a tennis ball farther than a basketball. Jim can throw a can of soda farther than a liter bottle of soda and he can throw a chair farther than a couch.
