The answer will depend on what aspect the 21 units refer to!
It could refer to the area of a rectangle that is 55 units long and 6 units deep.
The answer will depend on what characteristic of the moon is being measured in what measurement units.
Quantity K is metric for 1000. For units, it can also refer to Kelvin temperature. It can also refer to Kinetic energy.
You need to know that one mole is 6.022 x 1023 particles (atoms, molecules, ions, formula units, etc...).
Particles of one substance refer to the individual units that make up that specific substance. For example, in a sample of water, the particles would be the individual molecules of H2O. The properties of the substance are determined by the characteristics and interactions of its particles.
Cells are smaller than particles. Cells are the basic structural and functional units of living organisms, while particles refer to tiny pieces of matter, which can include molecules, atoms, or subatomic particles.
The smallest units of matter are the subatomic particles.
Yes, molecules are the smallest units of a substance that retain its characteristic properties. They are made up of atoms bonded together, and the arrangement of these atoms gives each molecule its unique properties.
The normal units are Pascals below standard atmospheric pressure. However, extremely high quality vacuums are sometimes measured in terms of the number particles per unit volume. Very specialised equipment can create vacuum of one trillionths of atmospheric pressure, or 10 nanoPascals. This is equivalent to around 100 particles per cubic centimetre. However, in outer space, it can go down to only a handful of hydrogen atoms (not even molecules) per cubic metre.

BUTT
The particles in most solids from structural units called crystals. Crystals are a solid substance that have a geometrically shaped form.
The energy given off by burning fossil fuels can be measured in joules or kilojoules. This measurement quantifies the amount of heat or energy produced during the combustion process. It helps in understanding the efficiency and environmental impact of using fossil fuels for energy generation.
1 kilograms and 1 square centimetres
Could be UNITS, as in units of measurements.
It could refer to the area of a rectangle that is 55 units long and 6 units deep.
