Question

Give the SI units for expressing these:

a. length,

b. area,

c. volume,

d. mass,

e. time,

f. force,

g. energy,

h. temperature.

Answer 1

The SI units for measurement include the meter for length, square meter for area, cubic meter or liter for volume, kilogram for mass, second for time, newton for force, joule for energy, and kelvin for temperature. These units are part of the metric system, which allows simple calculation and conversion.

Step-by-step explanation:

The SI units for expressing the measurements requested are:

• Length: meter (m)
• Area: square meter (m²)
• Volume: cubic meter (m³), or liter (L) for smaller volumes
• Mass: kilogram (kg)
• Time: second (s)
• Force: newton (N)
• Energy: joule (J)
• Temperature: kelvin (K)

These units are based on the International System of Units (SI), which is part of the metric system. They operate on a base-10 system, facilitating easy conversion with the use of metric prefixes. Some advantages of metric units include standardization across many scientific fields and nations, ease of calculation and conversion, and a simple relationship to physical properties.

Answer 2

1. length - metres
2. Area - meters squared
3. volume - cubic meters
4. Mass - newton
5. Time - seconds
6. Force - newton
7. energy - joules
8. temperature - degrees Celsius
