Question

The object transferring thermal energy will _________ energy and become cooler while the object gaining thermal energy will _________ energy and become warmer.

A spoon in a cup of hot coffee 

  • The ________ transfers thermal energy to the ______, making the _______ warmer

A cup of hot soup in a room

  • The _______ transfers energy to the ______, so the ______ becomes cooler

 

An ice cube in your hand

  • Your ________ transfers thermal energy to the ________, so it gains energy (and will start to melt).  You feel cold because you are LOSING thermal energy.

Particle Motion and Energy
Use the notes to answer the following questions in a different color/font
Define the following terms:
Kinetic Energy:energy due to movement
Temperature:the measure of the average kinetic energy of the particles
of a substance
Heat:the movement of thermal energy from a warmer substance to a
cooler substance
• Equilibrium:when both objects reach the same temperature
What happens to the temperature of a substance when the particles move
faster? Thermal energy is gained when a surface is heated. As a result, the
temperature increases and the particles move faster. As a material cools,
thermal energy is lost, allowing particles to move more slowly and the
temperature to drop.
What happens to the temperature of a substance when the particles move
slower? The kinetic energy of a substance's molecules can be determined by
its temperature. The higher the kinetic energy and the higher the temperature,
the faster the molecules of a material travel. The lower the kinetic energy and
the lower the temperature, the slower the molecules travel.
Objects/substances with more particles will have more thermal energy
If a beaker of water and a swimming pool have the same temperature,
which would have more thermal energy? Why? beaker because beaker
