a metal ball has a mass of 2kg and a volume of 6m cubed. What is its density?
0.33kg/m
What is the volume of a marble that has a mass of 3g and a density of 2.7g/mL?
1.1mL
Water has a density of 1g/mL. What is the mass of the water if it fills a 10mL container?
10g
A box 5cm long, 4cm wide, and 6cm high would have what volume?
120cm cubed
A graduated cylinder contains 17.5mL of water. When a metal cube is placed into the cylinder, its water level rises to 20.3mL. What is the volume of the cube in mL and in cm cubed?
2.8 mL
A solid is 5cm tall, 3cm wide, and 2cm thick. It has a mass of 129g. What is its density?
4.3g/cm cubed
how to find density
D= m/v
How to measure the density of a liquid?
D=m/v
How to measure the density of a solid?
D=m/v
How to find distatnce
D=st
how to find mass
M=dv
How to find speed/rate
S=d/t
how to find volume
V=m/d or lwh=V
define mass
a large body of matter with no shape
Define matter
everything that has mass and takes up space
define density
how compact something is
How to measure the mass of a liquid?
measure the mass of a graduated cylinder, add the liquid, measure the mass of that, and subtract the mass of the cylinder a
quantitative
measurments or nomer of something on the object (not temperature)
How to measure the volume of a liquid
pour the liquid into a graduated cylinder and measure the where it reached based on the spiked on the graduated cylinder
How to measure the mass of any solid?
put it on the scale
How to find time
t=d/s
define volume
the amount of space something takes up
In terms of volume, how do mL and cm cubed relate to one another?
they are the same but on different objects
How to properly measure the volume of an irregular object such as a rock?
use a glass and fill it up to where the water stops dripping out of the nozzle, place the object in and measure the amount of water that comes out of the nozzle in a graduated cylindar OR fill a graduated cylindar up to a certain point, place the object in and measure where the water level rised to, subtract that from the original amount of water
How to measure the volume of a solid object that isnt irregular?
use a glass and fill it up to where the water stops dripping out of the nozzle, place the object in and measure the amount of water that comes out of the nozzle in a graduated cylindar OR fill a graduated cylindar up to a certain point, place the object in and measure where the water level rised to, subtract that from the original amount of water OR lwh=v
Qualitative
what you observe of the object (not color)
When do you use a bar graph?
when the data is catigorial or not over time
When do you use a line graph?
when the data is going over time
When do you use a motion graph?
when the data is including speed, time, or distance
