Final answer:
To measure a heaping teaspoon of herbs, fill a teaspoon and allow herbs to form a mound above its edge without leveling off. For a pinch of salt, use your thumb and forefinger to take a small amount. In cooking, use grams or ounces for mass, and teaspoons, tablespoons, and cups for volume.
Step-by-step explanation:
To measure a heaping teaspoon of herbs, you would fill a teaspoon measuring spoon and then add enough herbs so that they form a small mound above the top edge of the spoon. It's important not to level off the top as you would for a level teaspoon. For a pinch of salt, you would take a small amount between your thumb and forefinger. Typically, this amount is less than an eighth of a teaspoon but can be adjusted to taste or as per recipe instructions.
When measuring the volume of a small amount of oregano or any other herbs and spices, the most practical tool would be measuring spoons that help you measure the precise quantity needed for your recipe.
For a handful of peanuts, you'd likely use grams or ounces as units of mass. In cooking, units such as teaspoons, tablespoons, and cups are commonly used to measure volume, based on the type and quantity of ingredients. For example, from LibreTexts™, we know 1 teaspoon is approximately 4.93 milliliters, aiding in these conversions.
In experiments comparing substances like sugar and salt, differences in mass when measured in the same volume imply different densities. You would determine which has a greater density by weighing equal volumes of both and comparing the masses. Cooking and baking often involve measuring by volume, although precise recipes will specify weight for better accuracy.
