TERMOMETRIA

Open Ended

How does the temperature of a material relate to the movement of its particles?

Multiple Choice

What is the significance of thermal energy in the movement of molecules?

• It determines the color of the material.

• It causes the molecules to vibrate and move constantly.

• It changes the shape of the molecules.

• It makes the molecules heavier.

Multiple Choice

What is thermal equilibrium?

• When two bodies in physical contact have no net energy flow between them and their temperatures are equal.

• When two bodies have different temperatures.

• When energy flows from one body to another indefinitely.

• When two bodies are isolated from each other.

Explain the significance of the Zeroth Law of Thermodynamics in measuring temperature.

Multiple Choice

Which of the following are types of thermometers?

• Thermometers for environments

• Industrial thermometers

• Clinical thermometer

• All of the above

Multiple Choice

Which of the following correctly represents the relationship between Celsius, Fahrenheit, and Kelvin temperature scales?

• (T_C/100) = (T_F-32)/180 = (T_K-273)/100

• (T_C/5) = (T_F-32)/9 = (T_K-273)/5

• (T_C/180) = (T_F-32)/100 = (T_K-273)/180

• (T_C/9) = (T_F-32)/5 = (T_K-273)/9

Multiple Choice

What happens to a bimetallic strip when the temperature increases in a fire alarm circuit?

• It bends and closes the circuit, triggering the alarm.

• It melts and disconnects the circuit.

• It remains unchanged.

• It contracts and opens the circuit.

Multiple Select

Which of the following statements about bimetallic strips are correct?

• They bend when heated due to different expansion rates of metals.

• They are used in thermostats to detect temperature changes.

• They are only used in air conditioning systems.

• They remain straight regardless of temperature changes.

Open Ended

How does the movement of molecules differ between a cold object and a hot object, and what is the significance of this difference in terms of thermal energy?

Fill in the Blanks

The coefficient of superficial expansion (β) is equal to

times the coefficient of linear expansion (α).

Multiple Choice

What is the relationship between temperature and the kinetic energy of the molecules in a material?

• As temperature increases, the kinetic energy of the molecules increases.

• As temperature increases, the kinetic energy of the molecules decreases.

• Temperature and kinetic energy are not related.

• As temperature decreases, the kinetic energy of the molecules increases.

Multiple Choice

Which of the following statements best describes the behavior of a hole in a metal plate when it is heated?
