1.2 Measurements Of Matter Flashcards
What is the U.S. customary system of measurement?
DISTANCE = Inch (in), foot (ft), yard (yd), and mile (mi) 1 foot = 12 inches 1 yard = 3 feet 1 mile = 5,280 feet 1 mile = 1,760 yards
WEIGHT = Ounce (oz), pound (lb), and ton (T) measure weight
1 pound = 16 ounces
1 ton = 2,000 pounds
VOLUME = Fluid ounce (fl oz), cup (c), pint (pt), quart (qt), and gallon (gal) 1 cup = 8 fluid ounces 1 pint = 2 cups 1 quart = 2 pints 1 gallon = 4 quarts
What is the U.S. customary system of measurement?
Distance
Inch (in), foot (ft), yard (yd), and mile (mi) measure the length of an object or the distance between two things.
1 foot = 12 inches 1 yard = 3 feet 1 mile = 5,280 feet 1 mile = 1,760 yards Weight Ounce (oz), pound (lb), and ton (T) measure weight.
1 pound = 16 ounces 1 ton = 2,000 pounds Volume Fluid ounce (fl oz), cup (c), pint (pt), quart (qt), and gallon (gal) measure liquid volume, which is the amount of space an object occupies.
1 cup = 8 fluid ounces
1 pint = 2 cups
1 quart = 2 pints
1 gallon = 4 quarts
What is distance?
The measure the length of an object or the distance between two things.
What is volume?
The amount of space an object occupies.
What is a meter?
The international standard unit of length and the fundamental unit of length in the metric system.
A meter is equal to 100 centimeters or approximately 39.37 inches.
What are the differences between the metric and English systems of measurement?
One reason for the wide-spread use of the metric system is that it seems easier to learn and remember. Instead of multiple words for units of measurement, such as inches, yards, and miles for length, the metric system uses only one word for length, the meter.
Give two examples of objects that are a meter in length.
A small area rug, A large picture frame
What are some different ways large or small distances can be measured?
Meters-
If a person needs a larger or smaller unit size to work with, he or she can simply add a prefix to the unit name to increase or decrease the size of the unit. So rather than changing the unit of measure, people can just change the prefix. This works with any unit of measure in the metric system: meter, gram, or liter.
What are the three temperature scales?
- Fahrenheit is the temperature scale that is common to the people in the United States. It sets the freezing point of water at 32 °F and the boiling point at 212 °F.
- The Celsius scale is used most often in other parts of the world. It sets the freezing point of water to 0 °C and the boiling point to 100 °C.
- For scientific measurements, there’s the Kelvin temperature scale. It sets 0 K as the coldest possible temperature. Water freezes at 273 K.
What is temperature?
the degree of heat present in a substance or object
What is mass?
Mass is a measure of the amount of matter in an object. Mass is usually measured in grams (g) or kilograms (kg). Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it. … One of the fundamental laws of chemistry is that of mass conservation.
Mass is not affected by gravity; weight is. Calculate weight by multiplying the object’s mass by gravity:
Weight= Mass x Gravity
What are derived units?
the measurement calculated from the measurement of other units
What is distance?
the length between objects
What is force?
a push or pull
What is time?
a measurement of how long it takes for an event to occur
What is weight?
the force of gravity on an object
What is temperature?
the degree of heat present in a substance or object
How is matter measured?
We can measure matter by its volume or its mass. We can also measure it by its temperature or its density. Volume measures how much space something takes up.
What does proportional mean?
Proportional: when two quantities always have the same size in relation to each other.
What is gravity?
Gravity: a force of attraction between two objects with mass
What is matter?
Matter: physical substance that occupies space
How is mass affected by the location of an object in space?
the strength of gravity on the body depends on the mass of the planet or moon. So, as the planets’ gravitational strength increases or decreases, the astronaut’s weight changes.
How does gravity affect weight?
More mass equals more weight. Here is an example. A truck with a mass of 3,500 kg will have more weight than a car with the mass of 1,500 kg on the same planet. If gravity changes, so does the weight. A smaller force of gravity will result in less weight. Here is an example. The gravity of the moon is about one-sixth the gravity of Earth. So your weight on the moon will be about one-sixth your weight on the Earth.
How is weight affected by the location?
While mass is a measurement of how much matter makes up an object, weight measures how much the force of gravity is acting on an object. When the astronaut moves from one object to the next, the amount of matter that makes up her body does not change, therefore her mass does not change. However, the strength of gravity on the body depends on the mass of the planet or moon. So, as the planets’ gravitational strength increases or decreases, the astronaut’s weight changes.
What is the important thing to remember about the relationship between mass and weight?
Mass is not affected by gravity; weight is. Calculate weight by multiplying the object’s mass by gravity: weight = mass x gravity
