Measurement Flashcards
Length is measured in what metric units?
Cm, m,mm
Volume is measured using what tools?
Ruler (LxWxH) for a regular solid
A beaker, graduated cylinder, measuring cup for liquids
Volume is measured in what units?
Liters, mL
Irregularly shaped solids cannot have volume measured using LxWxH. How do you measure it, then?
Water displacement using a graduated cylinder.
The formula for density is…
Density = mass/ volume
Substances that will float on a liquid must have a density that is ___________ than the liquid it is floating on.
Less than
What can you say about the density of an object that sinks in a liquid?
The density of that substance is greater than the liquid’s density.
In water displacement, how do you calculate volume of an irregularly shaped object?
Find initial volume in the graduated cylinder.
Place object in grad cylinder.
Read new volume
Final volume- initial volume= object’s volume.
density is…
the concentration of mass in an object, or the amount of matter in a given amount of space.
buoyancy
The tendency of an object to sink or float.
