Intro to Thermochemistry

Front

Energy due to motion is ____________ energy.

Back

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

Front

Heat flows from _______ to ______ objects.

Back

Heat flows from warmer to cooler objects.

Front

Which state of matter has loosely packed and unorganized particles?

Back

Gas is a state of matter where particles are loosely packed and unorganized.

Front

Thermal energy ALWAYS moves from _____ to _____.

Back

Thermal energy always moves from hot to cold.

Front

The point at which all particle motion stops.

Back

Absolute Zero is the theoretical temperature at which all particle motion stops.

Front

What is the definition of thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is a measure of the average kinetic energy of particles.

Front

What happens to the kinetic energy of particles as temperature increases?

Back

As temperature increases, the kinetic energy of particles also increases.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is the relationship between temperature and kinetic energy?

Back

Higher temperature corresponds to higher average kinetic energy of particles.
