Chemistry Mod 1 & 2 Vocabulary Quiz

Matter is anything that has [blank_start]mass[blank_end] and takes up [blank_start]space[blank_end]

In 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.

In the Metric System, the prefix [blank_start]micro[blank_end] is used for .000001

1 cubic centimeter is the same as 1 [blank_start]millimeter[blank_end].

[blank_start]Accuracy[blank_end] is an indication of how close a measurement is to the true value.

Precision is an indication of the [blank_start]scale[blank_end] on the measuring device that was used.

Significant figures are important because they tell us about the

When using scientific notation there

In chemistry, the greek character rho is used to stand for [blank_start]density[blank_end]

Density is mass per unit [blank_start]volume[blank_end]

Energy is defined as the ability to do [blank_start]work[blank_end].

Work is the force applied to an object times the [blank_start]distance[blank_end] that the object travels parallel to that force

Two kinds of energy are [blank_start]potential[blank_end], or stored energy and [blank_start]kinetic[blank_end], or energy in motion.

In 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].

Three 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.

To 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].

To convert Celsius to Kelvin, we use the formula, K = °C + [blank_start]273.15[blank_end]

1 [blank_start]calorie[blank_end] = 4.184 Joules

Specific 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.

Temperature 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

The [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.
