Question 1

Which state of matter is essentially incompressible?

Accepted Answer

Solids have a fixed volume and shape, and their particles are closely packed together. This makes them essentially incompressible as pressure applied to them cannot significantly change their volume. In contrast, liquids and gases can be compressed to some degree under high pressure.

Question 4

Which of the following is true of the relationship between density expressed in g/mL and specific gravity?

Accepted Answer

Specific gravity is the ratio of the density of a substance to the density of a reference substance (usually water at 4°C), and is therefore dimensionless. While density is expressed in g/mL or g/cm³, specific gravity has no units. However, they have the same numerical value when referring to the same substance and reference substance. Therefore, option C is the correct answer.

Question 5

Which of the following is true of ice, water and steam?

Accepted Answer

Ice, water, and steam are all forms of H2O and therefore are the same substance. The difference between them is their physical state, as they exist in solid, liquid, and gas forms respectively.

Question 6

At the 2008 Olympics the Jamaican runner Shelly Ann Fraser ran the 100. meter dash in world record time of 10.78 seconds. What is this speed in miles per hour? [1 mile = 1.609 km]

Accepted Answer

First, we need to convert 100 meters to miles by dividing by 1609 (since 1 mile = 1609 km):

100 meters ÷ 1609 = 0.06214 miles

Next, we need to convert seconds to hours by dividing by 3600 (since 1 hour = 3600 seconds):

10.78 seconds ÷ 3600 = 0.00299 hours

Finally, we can calculate the speed in miles per hour by dividing the distance by the time:

0.06214 miles ÷ 0.00299 hours = 20.8 mph

Therefore, the answer is C, 20.8 mph.

Question 7

At the 2008 Olympics the Ethiopian runner Kenisa Bekele won the 1.00 × 10⁴ meter run in 27 minutes, 1.17 seconds. What is this speed in miles per hour? [1 mile = 1.609 km]

Accepted Answer

1.00 × 10⁴ meters is equivalent to 10,000 meters. 27 minutes and 1.17 seconds is equivalent to 1621.17 seconds. So, the speed in meters per second is: Speed = Distance/Time Speed = 10000/1621.17 Speed ≈ 6.17 m/s Now we need to convert m/s to mph: 1 mile = 1609 meters (from 1 mile = 1.609 km) So, 1 meter/second = 2.237 miles/hour Therefore, the speed in miles per hour is: Speed ≈ 6.17 m/s × 2.237 miles/hour/meter Speed ≈ 13.8 mph Thus, the answer is choice D) 13.8 mph.

Question 8

Which of the following describes the compressibility of liquids?

Accepted Answer

The answer of Which of the following describes the compressibility...

Question 9

Aluminum has a density of 2.70 g/ cm³. What volume is occupied by a block of aluminum which weighs 4.32 kg?

Accepted Answer

To find the volume, use the formula: Volume = Mass / Density. Convert the mass from kg to g (4.32 kg = 4320 g). Then, Volume = 4320 g / 2.70 g/cm³ = 1600 cm³. Since 1 L = 1000 cm³, 1600 cm³ = 1.60 L.

Question 10

At the 2008 Olympics the Jamaican runner Usain Bolt ran the 200. meter dash in world record time of 19.30 seconds. What is this speed in miles per hour? [1 mile = 1.609 km]

Accepted Answer

The answer of At the 2008 Olympics the Jamaican runner...

Question 11

Which state of matter is highly compressible?

Accepted Answer

Gases are highly compressible because they have widely spaced particles that move freely and can be easily compressed into a smaller volume. Solids and liquids have particles that are tightly packed, making them less compressible.

Question 12

The dimensions of a piece of wood are 2.8 meters x 14 cm x 120 mm. What is the volume of this piece of wood?

Accepted Answer

To find the volume, convert all dimensions to the same unit (cm is convenient here): 2.8 meters = 280 cm, 14 cm = 14 cm, 120 mm = 12 cm. Volume = 280 cm × 14 cm × 12 cm = 47040 cm³, which is 4.7 × 10⁴ cm³.

Question 13

Dry ice is called dry ice because it passes directly from the solid state to the gaseous state (sublimes) under normal atmospheric conditions. Which of the following occurs during this transformation?

Accepted Answer

The volume of the sample increases because when dry ice sublimes, it changes from a solid directly into carbon dioxide gas, which occupies more space than the solid form.

Question 14

At the 2008 Olympics the Jamaican runner Usain Bolt ran the 100. meter dash in world record time of 9.69 seconds. What is this speed in miles per hour? [1 mile = 1.609 km]

Accepted Answer

First, we need to convert 100 meters to miles. 
100 meters = 0.0621371 miles

Next, we need to convert Bolt's time of 9.69 seconds to hours. 
9.69 seconds = 0.00269 hours

Now we can calculate his speed in miles per hour:

Speed (mph) = Distance (miles) / Time (hours) 
Speed (mph) = 0.0621371 miles / 0.00269 hours = 23.1 mph

Therefore, the correct choice is C.

Question 15

Mercury is the only metal which is a liquid at room temperature. The density of mercury is 13.6 g/cm³. What is the mass, in pounds, of 1.00 quart of mercury? [1 liter = 1.057 quart; 1 pound = 453.6 grams]

Accepted Answer

Question 16

The dimensions of a room are typically given in feet, but carpeting is sold by the square yard. How many square yards of carpet are required to cover the floor of a room which is 12 feet by 18 feet?

Accepted Answer

To find the area of the room in square feet, multiply the length and width:
Area = 12 feet x 18 feet = 216 square feet
To convert square feet to square yards, divide by 9:
216 square feet ÷ 9 = 24 square yards
Therefore, 24 square yards of carpet are required to cover the floor of the room. So, the correct answer is C.

Question 17

An unknown substance has a mass of 56.8 g and a volume of 23.4 mL. What is the density of this unknown substance?

Accepted Answer

Density is defined as mass divided by volume, so we can use the formula: density = mass/volume. Plugging in the given values, we get: density = 56.8 g/23.4 mL = 2.43 g/mL. Therefore, the correct answer is choice C.

Question 18

Which state of matter retains its volume but adapts its shape to that of its container?

Accepted Answer

Liquids retain their volume but can adapt their shape to that of their container, whereas solids retain both their volume and shape, and gases can expand to fill any container. Therefore, the correct choice is B) liquid.

Question 19

Question 20

A can of soda has a volume of 355 mL. The area of a circle is given as A = r², where r is the radius of the circle, so the volume of the can is given by V = ( r²)h, where h is the height of the can. If a particular can has a height of 12.2 cm what is the radius of the can?

Accepted Answer

We have V = Ah, where A = 11eab394_241c_cc2b_a5fb_e3c771c86934_TB1656_11 r² and h = 12.2 cm. Also, we know that the volume of the can is 355 mL, which is equal to 355 cm³. Therefore: 355 = A × 12.2 355 = (11 π r²) × 12.2 r² = 355 / (11 π × 12.2) r ≈ 3.04 cm So the radius of the can is approximately 3.04 cm, which is answer choice B.
