1. In a laboratory, you can find various pieces of apparatus depending on the type of lab. However, some common pieces of apparatus include microscopes, beakers, test tubes, Bunsen burners, pipettes, flasks, petri dishes, centrifuges, spectrophotometers, and autoclaves.

2. A physical quantity is a physical property of a phenomenon, body, or substance, that can be quantified by measurement. It has both magnitude and a unit. Examples of physical quantities include mass, volume, speed, time, temperature, and distance.

3. The SI base units are the standard units of measurement defined by the International System of Units (SI). There are seven SI base units. They are:

- Meter (m) for length
- Kilogram (kg) for mass
- Second (s) for time
- Ampere (A) for electric current
- Kelvin (K) for thermodynamic temperature
- Mole (mol) for amount of substance
- Candela (cd) for luminous intensity.
