Answer 1

kg- weighing machine
litre- weighing machine
grams - weighing machine

Answer 2

The physical quantities are as follows:-

Kilogram

The kilogram is the unit of mass.The gram is $\frac{1}{1000}$of a kilogram.The gram is defined as the mass  of 1 cubic centimeter volume water  at its melting point.

Mass is measured by kg and it is an inertial property.That is why objects tend to be at rest due to its mass.

Photons are massless and no other particle can travel faster than photons otherwise its mass will be negative.

The weight of a body is directly proportional to the mass of the body.

We can measure mass by using beam balance.

Gram

We can also gram by simple beam balance.

It is equal to one hundredth of a kilogram and it is used for measuring mass as well.

Litre

Litre is used for measuring the volume of the substance.

It can be measured by measuring cups.

Volume can also be found by the formula:Density=Mass/Volume.

Litre is one-thousandth of a cubic metre.

It is equal to : $\frac{1}{1000m^3}$

Metre

Metre is used to measure the length or breadth of an object.

It is equal to one-thousandth of a kilometer.

The other physical units include:-

Ampere

The ampere measures the amount of electric current passing through a body.

It can be measured by using ammeter.

Kelvin

Kelvin measures temperature and can be measured by using a thermometer.

The other units are:-

Luminous intensity(candela)

Time(second)

Amount of substance(mole)
