Considering the factors that influence diffusion (a) calculate the diffusion coefficient for copper in aluminum at 500°c. (b) what time will be required at 600°c to produce the same diffusion result (in terms of concentration at a specific point) as for 10 h at 500°c

Aman throws a football straight into the air. as it rises, it slows down. which type of energy is the football gaining?

Explain what happens at the saturation point when adding salt to water at room temperature.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
