What is the system of units used in science?
What is the Metric System of Measurement?
What is the definition of volume?
What is the amount of space that a substance takes up or occupies?
M= 25 g
V= 10 mL
What is the density?
p=m/v= 25g / 10 mL= 2.5 g/mL
Define plasma.
4th state of matter with the make up of ions and/or electrons
definite volume but indefinite shape
What are the units for mass?
What is grams or g?
What is the formula used to find the volume of a box?
What is Vbox = L x W x H ?
Define Density.
mass per unit of volume, with p symbol
Define control group.
the group that does not have the independent variable given for example the placebo.
definite shape and volume
solid
What are units for volume?
mL or cm3
Volume of a cube is found using Vcube= s3, how do I find the volume of a side in the calculator?
Put it in the calculator to the power of 1/3.
If the water in a graduated cylinder goes from 55 mL - 75 mL and the mass is 10g. What is the density?
p=m/v= 10 g/ (75 mL-55 mL)= 0.5 g/mL
liquid
Answer the following question:
The volume for a object is 20 mL and the mass is 5 g. What is the density?
What is 0.25 g/mL?
If I have the density and mass, how do I solve for volume?
What is p=m/v? Then I use the density triangle to solve for v.
v= m/p.
What is the density of a cement block that has a mass of 1000 g and measures as 3.5 cm x 7.6 cm x 2.4 cm?
p=m/v = 1000 g/ (3.5cm)(7.6cm)(2.4cm) =
15.7 g/cm3
Describe the differences between independent and dependent variables.
Independent variable is what is changed while dependent variable is what is observed to change based on the independent variable
indefinite shape and volume
gas
What are the units for density? P.S. there are 2 answers?
What is the g/cm3 or g/mL?
Describe how you would find the volume of an irregularly shaped object.
What is Water displacement?
What is the mass of a block of wood that has a density of .952 g/cm3 and measures 3.6 cm by 7.3 cm by 5.7 cm?
p=m/v
m= p x v = .952 g/cm3 x (3.6 cm x 7.3 cm x 5.7 cm) = 142.6 g
Define Neutron Star.
examples are fluorine and oxygen
gas
