SI units or International System of Units is defined as basic set of measurement of seven units. The physical quantities and base units are as follows:
Length is measured in meter (m), mass in kilogram (kg), time in second (s), electric current in ampere (A), temperature in Kelvin (K), luminous intensity in candela (cd) and amount of substance in mole (mol).
Therefore, SI units of physical quantities is known as base units and other units are known as derived units because they can derived from the SI units.
Thus, the correct match will be:




From the rest of the units, degree Fahrenheit is derived unit for temperature, gram is derived unit for mass, nanosecond is derived unit for time and candela is SI unit for luminous intensity.
Answer:
The new volume is 5.92 L, which is approximately 6 L
Explanation:
As the gas temperature increases, the molecules move faster and take less time to reach the walls of the container. This means that the number of crashes per unit of time will be greater. That is, there will be an increase (for an instant) in the pressure inside the container and the volume will increase.
So Charles's Law is one of the gas laws that relates the volume and temperature of a certain amount of gas at constant pressure and says that:
- If the temperature increases the volume increases
- If the temperature decreases the volume decreases
Mathematically this is expressed by:

When you want to study two different states, an initial and a final one of a gas, this law is expressed by:

In this case:
- V1: 8 L
- T1: 473 K
- V2: ?
- T2: 350 K
Replacing:

Solving:

V2=5.92 L
<u><em>The new volume is 5.92 L, which is approximately 6 L</em></u>
Answer:
Answer choice A
Explanation:
When an electron is transferred to another atom, both atoms involved become ions.
