Thermodynamics Review (A)

Which way does heat flow?

• hot to cold
• cold to hot
• it doesn't 
• out to sea, duh!

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.

High temperature is connected to:

• Low kinetic energy.
• High kinetic energy.
• Zero net energy.
• Equal kinetic energies.

Temperature is a measure of the...

• total energy in a substance
• total kinetic energy in a substance
• average potential energy in a substance
• average kinetic energy of molecules in a substance

The amount of thermal energy required to raise the temperature of one 1 gram of a substance by 1^o C is known as:

• Specific heat

• Heat of fusion

• Heat of vaporization

• Melting point

An ice cube is placed on a table and begins to melt.  The following conclusion can be made.

• Energy is being absorbed by the table which causes the cube to melt.
• Energy is being transferred from the table to the ice cube.
• Energy is being created by the air and table and making the cube heat up.

Two cups of water, one at 100^oC and the other at 50^oC are poured into a larger container. What would be the final temperature of the water?

• Less than 50^oC.
• Greaterr than 100^oC.
• Between  50^oC and 100^oC.
• The water temperature will rise and fall continually.
