Inspire Physical Science (Chapter 1)

A measurement standard is defined as

• a system of prefixes

• the distance between two points

• the exact quantity people agree to use for comparison

• the interval between two events

The prefix kilo- means

• 1,000

• 100

• 0.01

• 0.001

the prefix milli- means

• 1,000

• 100

• 0.01

• 0.001

The SI unit that is used to measure time is the

• kelvin

• kilogram

• second

• meter

The correct symbol for the SI unit of temperature is

• C

• F

• K

• s

The variable plotted on the horizontal or x-axis is called the

• dependent variable

• independent variable

• variable with the largest range

• variable with the smallest range

How many meters are there in 1865 cm?

• 0.1865

• 1.865

• 18.65

• 186.5

In a graph showing temperature change of a material over time, temperature change is the

• dependent variable

• independent variable

• variable with the largest range

• variable with the smallest range

The best type of graph to use to show how some fixed quantity if broken down into parts is

• bar graph

• line graph

• circle graph

• scatter graph

One benefit of the SI system is that it is

• based on units of 100

• not used to measure temperature

• based on multiples of ten

• not used in the United States
