7SCI-Q1-T2-Thermal Energy

How does the kinetic energy of particles relate to the perception of an object's temperature?

• Higher kinetic energy means the object feels cooler.

• Lower kinetic energy means the object feels warmer.

• Higher kinetic energy means the object feels warmer.

• Kinetic energy does not affect temperature perception.

What determines the temperature of an object according to the text?

• The color of the object.

• The average kinetic energy of its particles.

• The size of the object.

• The weight of the object.

Which temperature scale is used in science alongside the Celsius scale?

• Fahrenheit

• Kelvin

• Rankine

• Reaumur

How does one degree on the Celsius scale compare to one degree on the Fahrenheit scale?

• One degree Celsius is smaller than one degree Fahrenheit.

• One degree Celsius is nearly twice as large as one degree Fahrenheit.

• One degree Celsius is the same as one degree Fahrenheit.

• One degree Celsius is half the size of one degree Fahrenheit.

What is the significance of 0 K on the Kelvin scale?

• It is the boiling point of water.

• It is the freezing point of water.

• It is known as absolute zero.

• It is the average room temperature.

What is thermal energy a sum of in an object?

• Only the potential energy of the particles

• Only the kinetic energy of the particles

• The sum of potential and kinetic energies of all particles

• The chemical energy stored in the bonds

Why does a 1-liter pot of tea at 85°C have more thermal energy than a 0.2-liter cup of tea at the same temperature?

• Because the pot is made of a different material

• Because the pot has more particles

• Because the pot is at a higher temperature

• Because the pot is a different shape

Which of the following is NOT included in thermal energy?

• Kinetic energy of particles

• Potential energy of particles

• Chemical energy stored in bonds

• Total amount of matter

What is the unit of measurement for heat energy that is transferred to raise the temperature of a material?

• Joule

• Watt

• Newton

• Pascal

Which material has the highest specific heat according to the table?

• Aluminum

• Water

• Silver

• Iron
