A group of students painted four cans, placed 500 grams of water in each can, and measured the temperature of the water as shown in Figure 1.They placed the cans on a sunny windowsill for two hours and then measured the temperature again (Figure 2).

•Which statement correctly describes the significance of the temperature changes shown?

A The water molecules in the white can slowed down the most.

B The water molecules in the black can had the largest increase in average kinetic energy.

C The water molecules in the blue can have a lower average potential energy than the water molecules in the white can.

D The water molecules in the yellow can are moving at half the speed of the water molecules in the blue can.

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
