1. What quantity of heat is required to raise
the temperature of 450 grams of water
from 15°C to 85°C? The specific heat
capacity of water is 4.18 J/g °C.
a. 1.21 x 10-51
b. 1.32 x 105J
C. 1.52 x 10-5J
d. 1.52 x 105J

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?
