Temperature and Kinetic Energy Flashcard

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

How does temperature affect kinetic energy?

Back

As temperature increases, the kinetic energy of the particles in a substance also increases.

Front

What happens to the kinetic energy of particles in a solid as it is cooled?

Back

The kinetic energy of particles in a solid decreases as it is cooled.

Front

What happens to the speed of gas particles when the temperature decreases?

Back

The speed of gas particles decreases when the temperature decreases.

Front

What is the relationship between the speed of gas particles and temperature?

Back

Higher temperatures correspond to higher average speeds of gas particles.

Front

What happens to the kinetic energy of a liquid when it is heated?

Back

The kinetic energy of a liquid increases when it is heated.

Front

What is the effect of cooling on the kinetic energy of a gas?

Back

Cooling a gas decreases the kinetic energy of its particles.

Front

What is the definition of absolute zero?

Back

Absolute zero is the theoretical temperature at which a substance has minimum thermal energy, corresponding to 0 Kelvin.

Front

How does the kinetic energy of particles in a gas compare to that in a solid at the same temperature?

Back

Gas particles have higher kinetic energy than solid particles at the same temperature due to greater freedom of movement.
