Add universal indicator.
I would describe it as the answer is unknown. It's just really unknown. Or well the question here was unanswered until I'm answering it right now!
the answer to that is unknown to man kind
I would describe their weight in grams.
To find the density of an unknown liquid, you would first measure the mass of a known volume of the liquid using a balance. Then, you would measure the volume of the liquid using a graduated cylinder. Finally, divide the mass by the volume to calculate the density of the unknown liquid.
g/cm3
My guess would probably be a pixel. or a Point.
Here in the States we use pounds.
length
The range I believe, or that's what I put...
what method would you use to observe,measure and describe the physical propertie of the orange liquid without chang it ?ing
To calculate the density of an unknown substance, first measure its mass using a balance. Then, determine its volume by either measuring its dimensions and calculating the volume or using displacement method in a liquid. Finally, divide the mass by the volume to calculate the density of the unknown substance.
"Prop 13" would be a local measure and more information would be necessary to respond.
