Accepted Answer

Liters are the unit used to measure volume, specifically for liquids. Kilograms and pounds measure mass, while seconds measure time.

Question 7

Which of the following does the scientific method utilize?
A)Collecting relevant data
B)Forming a hypothesis
C)Testing the hypothesis
D)All of the above

Accepted Answer

The scientific method involves collecting relevant data, forming a hypothesis, and testing the hypothesis, making "All of the above" the correct choice.

Question 8

The scientific method tries to determine the nature of the problem.

Accepted Answer

The scientific method begins with identifying and defining the problem, which is the first step in understanding the nature of the issue to be investigated.

Question 9

How many meters are in 830 mm?
A)0.083 m
B)0.830 m
C)8.30 m
D)83.0 m

Accepted Answer

To convert millimeters to meters, you divide the number of millimeters by 1000 (since there are 1000 millimeters in a meter). Therefore, 830 mm divided by 1000 equals 0.830 meters.

Question 10

What is the conversion factor between centimeters and inches?
A)1 m / 2.54 cm
B)1 cm / 2.54 in
C)2.54 in / 1 cm
D)2.54 cm / 1 in

Accepted Answer

1 inch is equivalent to 2.54 centimeters, so the conversion factor is 2.54 cm per 1 inch.

Question 11

How many meters are in 0.645 km?
A)645 m
B)64.5 m
C)6450 m
D)6.45 m

Accepted Answer

1 kilometer equals 1000 meters, so 0.645 kilometers equals 645 meters.

Question 12

The length 3.0 ft contains how many centimeters?
A)300.0 cm
B)30.0 cm
C)9.14 cm
D)91.4 cm

Accepted Answer

1 foot is equal to 30.48 centimeters. Therefore, 3.0 feet is equal to 3.0 x 30.48 = 91.44 cm, which rounds to 91.4 cm.

Question 13

What is the difference between mass and weight?
A)All matter has weight, but not all matter has mass.
B)Weight is a measure of the pull of matter to a scale or measuring device, while mass is a measure of how much matter weighs.
C)All matter has mass, but only limited amounts have weight.
D)Weight is a measure of the pull of matter to the earth, while mass is a measure of how much matter is in a sample.

Accepted Answer

Weight is a measure of the force exerted by gravity on an object, which varies depending on the gravitational pull of the planet or celestial body the object is on. Mass, on the other hand, is a measure of the amount of matter in an object and remains constant regardless of location.

Question 14

Burning is an example of a physical change.

Accepted Answer

Burning is an example of a chemical change because it results in the formation of new substances.

Question 15

What is 3.83 m in cm?
A)383 cm
B)38.3 cm
C)3830 cm
D)0.00383 cm

Accepted Answer

To convert meters to centimeters, you multiply by 100 (since 1 meter = 100 centimeters). Therefore, 3.83 meters is 3.83 * 100 = 383 centimeters.

Question 16

How many millimeters are in a centimeter?
A)0.01
B)1000
C)100

B)Lt
C)Ls
D)lt

Accepted Answer

The correct abbreviation for liters according to the International System of Units (SI) is "L".

Question 19

Mass is always measured in grams.

Accepted Answer

Mass can be measured in various units depending on the system of measurement being used, such as kilograms, pounds, or ounces, in addition to grams.

Question 20

A gram is a smaller unit of mass than a kilogram.

Accepted Answer

A gram is a smaller unit of mass than a kilogram, with 1 kilogram equaling 1000 grams.
