Explanation:
Perfect Vacuum:
- A perfect vacuum refers to a state where there is no matter present, resulting in zero pressure.
- It is a space devoid of any particles, including gas molecules and atoms.
Absolute Zero Pressure:
- The condition of absolute zero pressure is achieved when there is no gas or vapor present in a given space.
- This implies that the pressure exerted by any gas molecules or atoms is zero.
Attainment of Absolute Zero Pressure:
- The temperature at which perfect vacuum or absolute zero pressure can be attained is -273.16°C.
- This temperature is known as absolute zero or 0 Kelvin, which represents the point at which all thermal motion ceases.
- At absolute zero, the particles have minimal energy and are motionless, resulting in zero pressure.
Therefore, the correct option is:
a) a temperature of -273.16°C
This temperature represents the theoretical limit at which a perfect vacuum can be achieved, leading to absolute zero pressure in a given space.
