A linear creep law is observed in an experiment on an alloy at high temperatures. Over time, the steady-state creep rate is observed to decrease. Briefly explain why. (b) Stainless steels are good high-temperature alloys because of the protection against oxidation provided by the passive oxide layer (Cr2O3). At high temperatures, Cr reacts with the Fe3C to form Cr23C6. What effect might this have on the corrosion resistance

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
