liters
You would most likely use milliters.
No it's a cup ! A cup is a unit of measure , just like a liter .
Ounces (Avoirdupois ounces, not fluid ounces. Fluid ounces measure volume, not mass.)
The unit used to measure the capacity of a soup pot is typically in liters (L) or milliliters (mL) for smaller pots. Capacity refers to the maximum volume of liquid the pot can hold. It is important to use the appropriate unit of measurement to accurately determine the volume of the pot and the amount of soup it can contain.
The answer depends on what characteristic of the soup can you wish to measure: mass, volume, temperature, radius, height, etc. There is no way to answer the question unless that information is provided.
The recommended uint in SI is litre (L) or the submultiple mL.
The SI (Le Systeme International d'Unites, International Unit) for length is Meter (m) but other units such as Centimeter (cm) or Millimeter (mm) can be used.
You are measuring the thermal energy of the hot soup, which is reflected in its temperature. Temperature is a measure of the average kinetic energy of the molecules in the soup.
The interior volume of the bowl. - ( Usually about 2 cups )
Either. A tin could described as 0.4 litres or 400 millilitres. In the UK they are often labelled in terms of the met mass (or weight).
As far as I am aware, CO is not a unit of measure.
