We diffusion bond two blocks of Cu and Ni. The wider the interdiffusion zone the stronger is the bonded component. When the process is conducted at 800 o C, the width of the interdiffusion zone is 102 mm, after 3 h. What would be the width, if the process were carried out at 900 o C and lasted for 5 h

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
