Thermodynamics

Match the following

• Objects in contact will eventually reach thermal equilibrium.

• 2nd Law of Thermodynamics

• A system's entropy approaches a constant value as its temperature approaches absolute zero.

• 3rd Law of Thermodynamics

• Entropy of a system increases.

• 1st Law of Thermodynamics

• Energy lost by a system is equal to the energy gained by its surroundings.

• 0th Law of Thermodynamics

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

Which statement is true about the ENTROPY?

• Entropy refers to DISORDER, the unusable energy that escapes a system.
• Entropy refers to the balance of temperature among two or more systems.
• Entropy refers to the average kinetic energy of the molecules.
• Entropy refers to the inability to destroy or create energy. 

As a system becomes more disordered, entropy

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

The transfer of thermal energy between objects of different temperatures is called...

• temperature
• heat
• internal energy
• none of these

It is possible to reach absolute zero

• true
• false

Heat travels from the sun to the earth by the process of...

• conduction
• convection
• radiation
• insulation

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.
