Dominic made the table below to organize his notes about mixtures. What mistake did Dominic make?

A: The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed.

B: There is a definite recipe to make each mixture, so the composition of a mixture is set.

C: Although it is possible to have more than one state, it is also possible to have only one state.

D: A single substance can be used to make a mixture if the substance is composed of more than one element.

Groups of organs that work together to complete a process in the body are called: a. cells b. tissues c. nerves d. systems

An internally reversible refrigerator has a modified coefficient of performance accounting for realistic heat transfer processes of where qin is the refrigerator cooling rate, qout is the heat rejection rate, and is the power input. show that copm can be expressed in terms of the reservoir temperatures tc and th, the cold and hot thermal resistances rt,c and rt,h, and qin, as where rtot rt,c rt,h. also, show that the power input may be expressed as 1.39 a household refrigerator operates with cold- and hot-temperature reservoirs of tc 5 c and th 25 c, respectively. when new, the cold and hot side resistances are rc,n 0.05 k/w and rh,n 0.04 k/w, respectively. over time, dust accumulates on the refrigerator’s condenser coil, which is located behind the refrigerator, increasing the hot side resistance to rh,d 0.1 k/w. it is desired to have a refrigerator cooling rate of qin 750 w. using the results of problem 1.38, determine the modified coefficient of performance and the required power input w under (a) clean and (b) dusty coil conditions. internally reversible refrigerator qout qin w high-temperature reservoir low-temperature reservoir th th,i tc,i tc high-temperature side resistance low-temperature side resistance w qin th tc qinrtot tc qinrtot copm tc qinrtot th tc

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.
