W hich 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.

A metal spoon is placed in one of two identical cups of hot coffee. Why does the cup with the spoon have a lower temperature after a few minutes?

Energy is removed from the coffee mostly by conduction through the spoon.

Energy is removed from the coffee mostly by convection through the spoon.

Energy is removed from the coffee mostly by radiation through the spoon.

The metal in the spoon has an extremely large specific heat capacity.

Heat can be transferred by the movement of particles in a material, by bulk motion of heated fluid, or through a vacuum as electromagnetic waves. What is the name of each process of thermal energy transfer, in the order given?

Conduction, convection, radiation

Convection, conduction, radiation

Radiation, convection, conduction

Conduction, radiation, convection

Using an air pump to compress air in a cylinder does work on the air in the cylinder. The result is

Air molecules gain kinetic energy, increasing the pressure in the cylinder

Air molecules lose kinetic energy, increasing the pressure in the cylinder

Air molecules lose kinetic energy, decreasing the pressure in the cylinder

Air molecules gain kinetic energy, decreasing the pressure in the cylinder

Your grandmother places a pitcher of iced tea next to a plate of warm, freshly baked cookies so that the pitcher and the plate are touching. You tell your grandmother that the plates are in thermal contact, which means that

heat flows from the warm plate to the cold pitcher.

heat flows within the warm plate but not within the cold pitcher.

heat flows from the warm plate to the cold pitcher and from the cold pitcher to the warm plate.

heat flows from the cold pitcher to the warm plate.

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

Cells in a body coming together

A metal spoon is sitting in a cup of coffee. Given their temperatures (in degrees Celsius), what can be said about the heat transfer between the coffee and the spoon?

Heat will be transferred from the spoon to the coffee.

Heat will be transferred from the coffee to the spoon.

The picture shows two completely identical mason jars. They're both filled with the same gas, only one of them has more in it (more molecules). What can you say about the pressures of both jars?

P 1 < P 2 (greater pressure in jar 2)

P 1 > P 2 (greater pressure in jar 1)

P 1 = P 2 (same pressure in both)

There's not enough info to tell

Temperature is a measure of the...

average kinetic energy of molecules in a substance

total kinetic energy in a substance

average potential energy in a substance

The temperature of a glass of cold water will eventually...

Match the temperature of the surrounding environment.

Always be colder than the surrounding environment.

Become warmer than the surrounding environment.

Ice cubes are added to a drink to cool it down. Describe the transfer of energy.

The coolness from the ice cube is transferred to the drink.

The ice transfers heat into the drink as the ice melts thereby cooling the drink.

The drink transfers energy to the ice causing the particles in the ice to move more rapidly – melting the ice

The average kinetic energy of the ice decreases because of the drink.
