Question

1) The amount of matter present in a substance is called​

Answer 1

• The amount of matter in a substance or object is measured by its mass.
• The kilogram (kg) is the most fundamental SI unit for mass, however lower quantities can be measured in grams (g).
• A balance is used to determine mass. A triple beam balance or an electronic balance can be used to measure mass in the lab, but the old-fashioned balance depicted below may give you a better concept of what mass is.
• The fruit in the left pan has the same mass as the iron item in the right pan if both sides of this balance are at the same level.
• In such situation, the fruit would be 1 kg in weight, which is the same as the iron.
• The fruit, on the other hand, is at a higher elevation than the iron, as you can see.
• This indicates that the fruit has a lower mass than the iron, i.e., the fruit weighs less than 1 kilogram.

Answer 2

• Mass measures the number of matter associate degree exceedingly|in a very substance or an object. the fundamental SI unit for mass is that the weight unit (kg).
• Mass is that the property of a figure that determines the strength of its mutual attractive force with alternative bodies.
• The unit of mass is that the weight unit.
• mass live the number of matter in associate object
• mass: Alive of the number of matter that associate object contains.
• weight: Alive of force that's adequate the attractive force pull on an associate object. a load of an associate object depends on its location.
• Mass is measured on a balance, by comparison, the thing against alternative objects with known lots. These objects are known as balance weights.
