Thermodynamics

A slower particle has a lower energy than an identical, faster particle.

• True
• False

When thermal energy is added to a substance, the substance's particles move:

• More rapidly at an increased diestance from each other.
• More rapidly with less distance between each other.
• More slowly with a greater distance between each other.
• More slowly with a reduced distance between each other.

A substance with a high specific heat:

• Is always extremely hot.
• Requires a lot of energy to become hot.
• Is not heavy.
• Does not requires a lot of energy to become hot.

Thermal energy always moves:

• From a high temperature object to a lower temperature object.
• From a lower temperature object to a higher temperature object.
• From an object with lower kinetic energy to an object with higher kinetic energy.
• From an object of higher mass to an object of lower mass.

The second  law of thermodynamics states that entropy of a system  tends to ______________. 

• increase
• decrease
• stay constant
• fluctuate wildly

The first law of thermodynamics states that energy is

• created
• destroyed
• conserved
• created and destroyed

The first law of thermodynamics states that the change in the internal energy of a system is equal to the difference in energy transferred to or from the system as heat and

• mass
• work done
• force
• pressure

Which state of H₂O  has the greatest entropy?

• Ice
• Water
• Vapor

As a system becomes more disordered, entropy

• remains the same
• increases
• decreases
• cannot be determined

Which is an example of decreasing entropy in a closed system?

• Boiling water

• Freezing water

• Cells in a body coming together

• Ice melting
