True, the metric system is now known as the international system of units.
<h3>What is the metric unit?</h3>
A system of measurement in which the basic units are the meter, the second, and the kilogram.
The Metric System is also known as The International System of Units. The metric system is called that because it is the system that the vast majority of countries in the world currently use.
The only countries that do not use this system are Liberia, Myanmar, and the United States, although schools in the United States are working to teach students both variations.

Answer:
Explanation:
Iron granules are separated from dust particles by using a magnet. The 'magnetic field' of the magnet will influence the iron granules that gets magnetized and attracted to the magnet.
Since liquid CO2 cannot exist at pressures lower than 5.11 atm, the triple point is defined as 56.6 °C and 5.11 atm.
Are CO2 liquids explosive?
Although it can impair judgement at high doses, carbon dioxide is neither poisonous nor combustible. Asphyxiation is typically seen as the primary risk associated with CO2. The Boiling Liquid Expanding Vapour Explosion, however, is a serious risk connected to compressed CO2 (BLEVE)
What PSI does CO2 turn into liquid at?
Only at pressures more than 5.1 atm does liquid carbon dioxide form; the triple point of carbon dioxide is approximately 518 kPa at 56.6 °C. Depending on the pressure, the liquid's boiling point ranges from -70°F to +88°F. The expansion ratio when vaporised at 60°F is 535:1. CO2 is a gas or liquid.

If we takes 11. 2 kj of energy to raise the temperature of 145 g of benzene from 23. 0°c to 68. 0°c, then the specific heat of benzene is
1716.475 J/kg.°C.
Specific Heat capacity is given as
Q = cm(t₂-t₁) ................
Where Q = quantity of heat, c = specific heat of benzene, m = mass of benzene, t₁ = initial temperature, t₂ = final temperature.
=
Given:
Substitute into equation 2.
Hence the specific heat of benzene =
