A student measured out 1 kg samples of each substance below on a triple beam balance. Next, the student heated each sample on a
hot plate, increasing the temperature of each sample by 10°C as
measured with a Celsius
thermometer. Based on the given
specific heat capacities, which substance required thr most heat input
for this temperature increase?
A Water, Cp= 4186 J/kg•°C
B Silver, Cp = 234 J/kg•°C
C Copper, Cp = 387 J/kg•°C
D Aluminum, Cp = 899 J/kg•°C

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?
