Identify correct unit of a measurement. Distinguish Between mass and volume
To identify the correct unit of measurement, you generally need to know the physical quantity being measured. Here are some examples:
1. Length - the unit of measurement is typically meters (m), although it can also be expressed in other units like centimeters (cm) or kilometers (km).
2. Mass - the unit of measurement is typically grams (g) or kilograms (kg), although it can also be expressed in other units like pounds (lb) or ounces (oz).
3. Time - the unit of measurement is typically seconds (s), although it can also be expressed in minutes (min), hours (hr), or days (d).
4. Temperature - the unit of measurement is typically degrees Celsius (°C), although it can also be expressed in degrees Fahrenheit (°F) or Kelvin (K), among others.
Now let's distinguish between mass and volume:
Mass:
Mass is a measure of the amount of matter in an object. It remains the same regardless of the location of the object. The most common unit for mass is the kilogram (kg). Other units include gram (g) and tonne (t).
Volume:
Volume is the amount of space occupied by an object or substance. It can be measured in various units depending on the context. For liquids, volume is typically measured in liters (L) or milliliters (mL). For solids, volume is often measured in cubic meters (m³) or cubic centimeters (cm³).
To distinguish between mass and volume:
1. Definition: Mass refers to the amount of matter in an object, while volume refers to the space occupied by an object or substance.
2. Units of Measurement: Mass is typically measured in grams or kilograms, while volume is typically measured in liters or cubic meters.
3. Independence: Mass is independent of location, while volume can be affected by the shape and arrangement of an object.
