module 3 metric system

A liter is equivalent to: 1 cm3 1 m3 1 mm3 1 dm3

1 dm3 Use the fact that 1mL=1cm3 to determine the equivalent volume of 1L. If 1mL=1cm3, then 1L=1,000mL=1,000cm3. Now, convert 1,000cm3 into m3. 1,000cm3×(1m100cm)3=1×10−3m3 Now, use the fact that 1m=10dm to determine the volume of 1dm3 in m3. 1dm3×(1m10dm)3=1×10−3m3 Therefore, 1L=1×10−3m3=1dm3.

35gigatons equals __________. 3.5×10−9tons 3.5×10−10tons 3.5×109tons 3.5×1010tons

3.5×1010tons The prefix "giga" means 109, so it can be written as the following. 35gigaton=35×109tons To write the number in scientific notation, the decimal part must be between 1 and 10. Move the decimal point in 35 to the left one place, and, since this makes the number smaller by a power of 10, add 1 to the exponent on 10 to compensate.35×109tons=3.5×1010tons.

Which of the following statements BEST describes the SI system of unit? An updated version of the English System of Measurement. An expansion of the metric system. Another version of the Imperial System of Measurement. The only system of measurement that is used throughout the world.

An expansion of the metric system. The SI system is used in the scientific and medical fields and is an expanded form of the metric system.

In what temperature scale does water boil at 100∘? Yes that's right. Keep it up! Fahrenheit Kelvin Celsius Grams

Celsius Water boils at 100 degrees in Celsius, 373.15 degrees in Kelvin and 212 degrees in Fahrenheit. The gram is a unit of mass, not temperature.

Which statement BEST explains why temperature is an intensive property? It is a property that is independent of the amount of matter in a sample. It is a property that depends on the amount of matter in a sample. It is a property that is only viewable when a substance is undergoing a chemical reaction. It is a property that is dependent on the chemical properties of the matter.

It is a property that is independent of the amount of matter in a sample. Temperature is an intensive property because it is independent of the amount of matter for a given sample.

What is significant about the temperature of 0K? It is the temperature at which matter has no density. It is the temperature at which atoms stop moving. It is the temperature at which atoms cease to exist. It is the temperature at which water molecules freeze

It is the temperature at which atoms stop moving. A temperature of 0K is absolute zero and is the point at which motion of atoms stop.

In November 2018, the kilogram was redefined in terms of Planck's constant. Directly prior to this, the kilogram was based on: Select the correct answer below: a cylinder of platinum-iridium alloy the mass of a liter of water the mass of a king's crown the mass of a gold bar

a cylinder of platinum-iridium alloy The kilogram was originally defined to be the mass of one liter of water; however, there is some variance in this quantity with temperature and pressure. A more rigid definition for the kilogram was adopted In the late 19th century, which defined the mass of one kilogram as the mass of a metal cylinder of platinum-iridium alloy, which is stored in France.

Which is the longest distance? a meter a kilometer a megameter a terameter

a terameter A terameter is 1012 meters, whereas a megameter is 106 meters and a kilometer is 103 meters.

Which of the following is NOT a unit used in the SI system? Select the correct answer below: ampere atomic mass unit kilogram meter

atomic mass unit Ampere, gram. and meter are all units in the SI system. An atomic mass unit is a commonly used measurement in chemistry, but it is not part of the SI system.

Which prefix means one one-hundredth? Perfect. Your hard work is paying off 😀 centi deci milli kilo

centi Deci is one tenth, milli is one one-thousandth, and kilo is one thousand.

Which of the following is NOT a base unit used in the SI system of measurement? Select the correct answer below: second milliliter mole meter

milliliter The second, the mole, and the meter are all SI base units. Milliliter is a prefixed unit, with the base unit of "liter."

A temperature change of one Kelvin is the same magnitude as a change of Select the correct answer below: one degree Celsius one degree Fahrenheit both one degree Celsius and Fahrenheit none of the above

one degree Celsius Kelvin and Celsius have degrees of the same magnitude, they simply have different starting points, 0 K and −273∘C are both equal to absolute zero.

Which is the shortest length of time? one microsecond one nanosecond one millisecond one decisecond

one nanosecond A nanosecond is 10−9 seconds, whereas a microsecond is 10−6 seconds, a millisecond is 10−3 seconds, and a decisecond is 10−1 seconds.

oday, the meter is based on: Select the correct answer below: a meter stick the height of a king a fraction of the distance from the equator to the north pole the distance light travels in a particular fraction of a second

the distance light travels in a particular fraction of a second The meter was once defined as a particular fraction of the distance from the equator to the north pole, but it was eventually revised to be more universal.

The unit cubic meters is associated with: mass volume density length

volume The unit of cubic meters is associated with volume, which is the amount of space occupied by an object. The SI unit for volume is simply derived from the SI unit for length (the meter).
