Multiple Choice

Which of the following best describes the relationship between temperature and kinetic energy?

• Higher temperature means more kinetic energy in molecules.

• Lower temperature means more kinetic energy in molecules.

• Temperature and kinetic energy are not related.

• Kinetic energy only increases when temperature is at freezing point.

Multiple Choice

Which of the following best describes heat?

• The amount of thermal energy all bodies and objects contain and give away to the surrounding environment.

• The temperature of an object.

• The energy stored in chemical bonds.

• The amount of light an object emits.

Multiple Choice

Which substance has the highest specific heat capacity according to the table?

• Water

• Ethanol

• Aluminum

• Copper

Multiple Choice

What is the purpose of heating an object to a specific temperature before placing it in room temperature water when measuring heat transfer?

• To ensure the object and water start at different temperatures for heat transfer to occur

• To sterilize the object before the experiment

• To prevent the object from floating

Multiple Choice

Which of the following statements best explains how to determine if more or less heat energy was transferred to the water?

• By comparing the change in water temperature before and after the experiment

• By measuring the mass of the metal only

• By checking the color of the water

Multiple Choice

If two different materials of equal mass are placed in water, what does a greater temperature change in the water indicate about the heat energy transferred? Select all that apply.

• More heat energy was transferred

• Less heat energy was transferred

• The water lost energy

Multiple Choice

Which metal, lead or iron, transferred more heat energy to water, and how do you know from the data?

• Lead transferred more heat because its temperature changed more.

• Iron transferred more heat because it changed the water temperature by a greater amount.

• Lead and iron transferred heat equally because their final temperatures were the same.

Multiple Choice

Based on the data and explanation in slides 2 and 3, what is the relationship between the starting temperature of a material and the amount of heat energy transferred to water?

• Lower starting temperature results in more heat energy transferred.

• Higher starting temperature results in more heat energy transferred.

• Starting temperature does not affect heat energy transferred.

Multiple Choice

What claim can you make about the relationship between the mass of an iron object and the amount of energy transferred to water, based on the data provided?

• Less mass results in more heat energy transferred.

• More mass results in more heat energy transferred.

• Mass does not affect heat energy transfer.

• Heat energy transfer is only affected by temperature, not mass.

Multiple Choice

Which of the following is an example of a dependent variable in a plant growth experiment?

• Amount of water given to the plant

• Type of soil used in the pot

• Size of the plant

Multiple Choice

How does temperature relate to the kinetic energy of molecules in a substance?

• Higher temperature means more kinetic energy.

• Lower temperature means more kinetic energy.

• Kinetic energy only increases with pressure, not temperature.
