Measurement Units
- Volume is the amount of space a substance occupies.
- Liter (L) and milliliter (mL) are common units for measuring volume.
- The kilogram (kg) is the SI unit of mass and is used for larger masses.
- The gram (g) is the metric unit of mass and is used for smaller masses.
- Temperature is measured in Celsius (°C) in the metric system and Kelvin (K) in the SI system.
- Water freezes at 0°C.
###Â Identifying Units
- Mass: A bag of onions has a mass of 2.6 kg.
- Length: A person is 2.0 m tall.
Types of Errors
- Random errors occur due to unpredictable changes, such as temperature fluctuations or pH changes.
- Blunders are human errors, such as adding the wrong chemical or using the wrong media in an experiment.
