Yes "feldspar" is one of the minerals on Moh's scale of hardness.
No, the hardness of a mineral does not affect its performance in the streak test. The streak test measures the color of the powdered form of a mineral when it is scratched against a streak plate, regardless of the mineral's hardness.
No, the hardness of a mineral does not affect its performance in the streak test. The streak test is determined by the color of the powder left behind when the mineral is scratched against a ceramic plate, not the hardness of the mineral itself.
hardness
Hardness test: Determining the mineral's hardness using Mohs scale. Streak test: Observing the color of the mineral's powdered form. Acid test: Reacting the mineral with acid to observe effervescence. Magnetism test: Checking if the mineral is attracted to a magnet. Cleavage or fracture test: Assessing how the mineral breaks when subjected to stress.

No. Streak color is distinct of mineral hardness. They are separate properties.
Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.
The Moh's scale is used to test the hardness of a mineral. It will be tested by a fingernail scratching it.
Scratching a mineral with a nail is a test of hardness. The Mohs scale of mineral hardness ranks minerals from 1 (softest) to 10 (hardest), with talc being the softest and diamond being the hardest. If a mineral can be scratched by a nail (with a hardness of around 2.5), it would be classified as having a hardness lower than 2.5 on the Mohs scale.
Mineral hardness is tested on a glass plate or usually a finger nail.
You could test for the property of hardness by seeing which mineral scratches the other. The mineral that scratches the other is the harder one.
The scratch test measures a mineral's hardness, which is its resistance to being scratched. This property is identified by comparing the hardness of a mineral to the hardness of known minerals on the Mohs scale.

It is called a streak and its purpose is to find the hardness of the mineral.
