This diagram shows two closed, insulated compartments, where no energy can escape. Both compartments contain water of equal volume but varying temperatures of 50°C and 25°C respectively.

If the temperature of the water measuring 50°C decreased by 15°C, the temperature of the water measuring 25°C would

also decrease by approximately 15°C.

increase by approximately 15°C.

none of the options

remain the same.

What is always the direction of heat transfer?

From matter at higher temperature to matter at lower temperature

From matter at lower temperature to matter at higher temperature

From an object with less thermal energy to an object with greater thermal energy

From an object of greater mass to an object of less mass

A celebrity chef is looking for a metal-plated pan that she can heat to as high a temperature as possible for a given input of energy. Her different pan options are copper, iron, and aluminum. All of the pans have the same mass. Observe the metal specific heat capacities shown in the table below. Which metal pan should the chef not choose because it undergoes the smallest temperature change for a given input of energy?

The chef can choose any of the three pans, because all three pans will undergo the same amount of temperature change.

The chef should not choose the aluminum pan.

The chef should not choose the copper pan.

The chef should not choose the iron pan.

During a lab, a student stirs crushed ice into warm water. How will this system behave, according to the second law of thermodynamics?

The ice cubes will lose heat and the warm water will gain heat until the temperature in the system is uniform throughout.

Both the ice cubes and the warm water will gain heat. Thermal equilibrium will not be reached.

The ice cubes will gain heat and the warm water will lose heat until the temperature in the system is uniform throughout.

Both the ice cubes and the warm water will lose heat. Thermal equilibrium will not be reached.

The diagram shows a copper cylinder being heated by a Bunsen burner. Point A is at the heat source. In which direction will the heat flow?

The heat will flow toward point D only.

The heat will flow toward points B, C, and D.

The heat will remain at point A.

The heat will flow toward points B and C only.
