When heat energy is added to water in a pot on a stove, what changes occur to the water?

• Particles move faster, and temperature increases.

• Particles move slower, and temperature increases.

• Particles move faster, and temperature decreases.

• Particles move slower, and temperature decreases.

Answer explanation

When heat energy is added to water, the particles gain energy and move faster, leading to an increase in temperature. This is why the correct answer is that particles move faster, and temperature increases.

A student wants to determine if the color of a cup will affect the temperature of the water contained in the cup. The student selects three different-colored cups, places 200 mL of water in each cup, and places all three cups in the Sun for 10 minutes. What tool should the student use to check which cup absorbed the most heat after 10 minutes?

• graduated cylinder

• spring scale

• stopwatch

• thermometer

Answer explanation

The student should use a thermometer to measure the temperature of the water in each cup. This will help determine which cup absorbed the most heat, as the thermometer provides the necessary temperature readings.

A student selects three identical Styrofoam cups (1, 2, and 3), paints one white and one black, and covers the outside of the third with aluminum foil, as shown. The student fills each cup with an equal volume of water at room temperature and places the cups in sunlight. After three hours, the student observes that the water in cup 3 is the coolest. Which statement correctly explains the student’s observation?

• The aluminum foil does not let light pass through it.

• The aluminum foil is too thin to absorb heat.

• The aluminum foil absorbs heat from the surroundings.

• The aluminum foil reflects the light back toward the atmosphere.

Answer explanation

The aluminum foil reflects the light back toward the atmosphere, preventing heat absorption. This keeps the water in cup 3 cooler compared to the painted cups, which absorb more heat from sunlight.

A student took an empty bowl, placed it in an oven, and heated it. She then added water to the hot bowl and dropped in an ice cube. Which is the correct direction of heat flow in the bowl of water resulting in the melting of the ice cube?

• ice cube → water → bowl

• ice cube → bowl → water

• bowl → ice cube → water

• bowl → water → ice cube

Answer explanation

Heat flows from the hot bowl to the water, raising its temperature, and then to the ice cube, causing it to melt. Thus, the correct direction of heat flow is bowl → water → ice cube.

A student performs an investigation to demonstrate the process of heat transfer by conduction. She attaches metal paper clips onto a metal rod equal distances apart using candle wax. The student then heats one end of the rod on a flame. Which description shows the safest way to perform the investigation?

• (Hand holding metal rod directly)

• (Gloved hand holding metal rod)

• (Hand holding metal rod directly, but on the other side)

• (Gloved hand holding metal rod on the other side)

Answer explanation

The safest way is to use a gloved hand holding the metal rod on the other side. This prevents burns from heat transfer while keeping a safe distance from the flame.

Which cooking utensil would be the best conductor of heat energy when placed in boiling water?

• metal whisk

• plastic fork

• rubber spatula

• wooden spoon

Answer explanation

The metal whisk is the best conductor of heat energy among the options. Metals efficiently transfer heat, making the whisk ideal for use in boiling water, unlike plastic, rubber, or wood, which are poor conductors.

A student fills four cups made of different materials each with 50 mL of water at the same temperature and places them in the Sun. The student records the temperature of each of the cups after 15 minutes in a data table. Time | Temperature of Cup 1 (°C) | Temperature of Cup 2 (°C) | Temperature of Cup 3 (°C) | Temperature of Cup 4 (°C) 0 min | 20.0 | 20.0 | 20.0 | 20.0 15 min | 22.0 | 21.0 | 21.3 | 20.5 Based on the data, which cup is most likely made of copper (metal)?

• Cup 1

• Cup 2

• Cup 3

• Cup 4

Answer explanation

Cup 1 has the highest temperature increase (2.0 °C), indicating it absorbed heat most effectively. Copper, being a good conductor, would heat the water more quickly than the other materials, making Cup 1 the most likely candidate.

A student places a cork upright in a wave tank filled with water. The image shows how a wave ripples across the tank. The cork does not change its position within the wave; instead, it moves up and down in its original position. What can be concluded about mechanical waves from this activity?

• Mechanical waves carry the particles of mediums along with the waves.

• Mechanical waves can move through empty spaces.

• Mechanical waves transfer energy but not matter.

• Mechanical waves do not carry energy.

Answer explanation

The cork's up-and-down motion shows that while energy is transferred through the wave, the cork itself does not move horizontally. This illustrates that mechanical waves transfer energy but not matter.

Which statement is true about cells?

• All cells are the same size.

• Many organisms are made up of more than one cell.

• All organisms are made up of one cell.

• Cells are the smallest unit of nonliving material.

Answer explanation

The correct statement is that many organisms are made up of more than one cell, as multicellular organisms exist, while unicellular organisms consist of just one cell. The other statements are incorrect.

A student listed some characteristics of an organism. 1. It possesses transport systems. 2. Only the surface cells of the organism are in contact with the outer environment. Which other characteristic should the student include in the list?

• A. Injury or death of one cell can result in death of the organism.

• B. All cells can directly exchange substances with the environment.

• C. It has a single basic unit of life which carries out all the life processes.

• D. Its cells are differentiated to perform specialized functions.

Answer explanation

The organism's cells are specialized, indicating differentiation, which is essential for complex functions. This aligns with the transport systems and limited environmental contact, making option D the best choice.
