What is the purpose of placing a Bunsen burner under a beaker of water in the illustration?

• To cool the water

• To transfer energy from the flame into the water

• To freeze the water

• To measure the mass of the water

Answer explanation

The purpose of placing a Bunsen burner under a beaker of water is to transfer energy from the flame into the water, heating it. This process is essential for experiments that require the water to reach a certain temperature.

If you want to raise the temperature of water by one degree, what do you need to know?

• The color of the water

• The amount of energy required

• The shape of the container

• The type of gas used in the Bunsen burner

Answer explanation

To raise the temperature of water by one degree, you need to know the amount of energy required. This is because temperature change is directly related to the energy input, not the color, shape, or type of gas used.

Why does the amount of each substance in the pizza matter when considering which will reach 200 degrees Celsius first?

• Because the oven temperature changes

• Because the amount affects how quickly each substance heats up

• Because the pizza will taste different

• Because the cheese melts faster

Answer explanation

The amount of each substance affects its specific heat capacity, meaning larger amounts require more energy to heat up. Thus, substances with less mass will reach 200 degrees Celsius faster than those with more mass.

Summarize what is needed to calculate the amount of energy required to raise the temperature of a substance.

• The mass of the substance, the specific heat capacity, and the temperature change

• The color of the substance and the room temperature

• The volume of the container and the air pressure

• The boiling point and freezing point of the substance

Answer explanation

To calculate the energy needed to raise a substance's temperature, you need the mass of the substance, its specific heat capacity, and the temperature change. These factors determine the total energy required.

What is the specific heat capacity of water in its liquid state, as mentioned in the material?

• 4186 J/kg°C

• 1670 J/kg°C

• 450 J/kg°C

• 3500 J/kg°C

Answer explanation

The specific heat capacity of water in its liquid state is 4186 J/kg°C, which is the highest among the given options. This value indicates how much energy is required to raise the temperature of 1 kg of water by 1°C.

Which substance requires the least amount of energy to raise the temperature of 1 kg by 1 degree Celsius, according to the material?

• Iron

• Water

• Oil

• Copper

Answer explanation

Iron has a lower specific heat capacity compared to water, oil, and copper, meaning it requires less energy to raise its temperature by 1 degree Celsius. Therefore, iron is the correct choice.

Why is well water commonly used as a coolant in engines?

• It is cheap and easy to find

• It has a fairly high specific heat capacity

• It freezes at a lower temperature

• It is less dense than other liquids

Answer explanation

Well water is commonly used as a coolant in engines because it has a fairly high specific heat capacity, allowing it to absorb and retain heat effectively, which helps maintain optimal engine temperatures.

Why does land experience a much greater increase in temperature than water when the same amount of energy is applied?

• Land has a higher heat capacity

• Land has a lower heat capacity

• Land reflects more sunlight

• Land contains more water

Answer explanation

Land has a lower heat capacity than water, meaning it requires less energy to increase its temperature. Therefore, when the same amount of energy is applied, land heats up more quickly than water.
