1Matter is anything that has [blank_start]mass[blank_end] and takes up [blank_start]space[blank_end]
- Amass
- Bspace
2In the Metric System the base unit for mass is [blank_start]gram[blank_end], the base unit for distance is [blank_start]meter[blank_end], the base unit for [blank_start]volume[blank_end] is liter and the base unit for [blank_start]time[blank_end] is second.
- Agram
- Bmeter
- Cvolume
- Dtime
3In the Metric System, the prefix [blank_start]micro[blank_end] is used for .000001
- Amicro
41 cubic centimeter is the same as 1 [blank_start]millimeter[blank_end].
- Amillimeter
5[blank_start]Accuracy[blank_end] is an indication of how close a measurement is to the true value.
- AAccuracy
6Precision is an indication of the [blank_start]scale[blank_end] on the measuring device that was used.
- Ascale
7Significant figures are important because they tell us about the
- Aaccuracy of the measurements used.
- Bprecision of the measurements used.
8When using scientific notation there
- Acan be as many numbers to the left of the decimal point as your calculator indicated
- Bshould be no numbers to the left of the decimal point
- Cshould have all the numbers to the left of the decimal point
- Dshould have one digit on the left side of the decimal point
9In chemistry, the greek character rho is used to stand for [blank_start]density[blank_end]
- Adensity
10Density is mass per unit [blank_start]volume[blank_end]
- Avolume
11Energy is defined as the ability to do [blank_start]work[blank_end].
- Awork
12Work is the force applied to an object times the [blank_start]distance[blank_end] that the object travels parallel to that force
- Adistance
13Two kinds of energy are [blank_start]potential[blank_end], or stored energy and [blank_start]kinetic[blank_end], or energy in motion.
- Apotential
- Bkinetic
14In order to arrive at a scientific law, first a person observes, then forms a [blank_start]hypothesis[blank_end], then tests the hypothesis with [blank_start]experiments[blank_end]. After being confirmed by rigorous experimentation, the hypothesis is considered a [blank_start]theory[blank_end]. A theory that is continuously confirmed by observation becomes a scientific [blank_start]law[blank_end].
- Ahypothesis
- Bexperiments
- Ctheory
- Dlaw
15Three temperature scales are commonly used. [blank_start]Fahrenheit[blank_end] is commonly used by the public in the United States. [blank_start]Celsius[blank_end], or centigrade, is a metric unit, and [blank_start]Kelvin[blank_end], often called the absolute temperature scale, is used for very cold temperatures.
- AFahrenheit
- BCelsius
- CKelvin
16To convert Celsius to Fahrenheit, we use the formula °F= ( [blank_start]9[blank_end] / [blank_start]5[blank_end] ) (°C) + [blank_start]32[blank_end].
- A9
- B5
- C32
17To convert Celsius to Kelvin, we use the formula, K = °C + [blank_start]273.15[blank_end]
- A273.15
181 [blank_start]calorie[blank_end] = 4.184 Joules
- Acalorie
19Specific heat is the amount of [blank_start]heat[blank_end] necessary to raise the temperature of 1 [blank_start]gram[blank_end] of a substance by [blank_start]1[blank_end] degree Celsius.
- Aheat
- Bgram
- C1
20Temperature change in an object is related to the amount of heat it absorbs or releases by the equation: [blank_start]q[blank_end]=[blank_start]m[blank_end][blank_start]c[blank_end]∆T
- Aq
- Bm
- Cc
21The [blank_start]calorimetry[blank_end] equation tells us that any heat [blank_start]gained[blank_end] by the calorimeter and the water must have been [blank_start]lost[blank_end] by the object placed in the calorimeter.
- Acalorimetry
- Bgained
- Clost
