Question

You have a steak that is 20 cm in length, 12 cm in width, and 4 cm thick. Assuming that the calculated diffusion coefficient for the marinade in steak is the same as that for meatballs, how long should you marinade the steak if you want it to reach the center?

A) 12 hours
B) 6 hours
C) 8 hours
D) 4 hours

Answer 1

To determine how long you should marinade the steak for it to reach the center, you need to consider the diffusion of the marinade through the steak. The time required for diffusion depends on the thickness of the steak and the diffusion coefficient of the marinade. Unfortunately, without knowing the diffusion coefficient, we cannot determine the exact time for marinading the steak.

Step-by-step explanation:

To determine how long you should marinade the steak for it to reach the center, you need to consider the diffusion of the marinade through the steak. Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. The time required for diffusion depends on the thickness of the steak and the diffusion coefficient of the marinade.

In this case, we are assuming that the calculated diffusion coefficient for the marinade in steak is the same as that for meatballs. Therefore, we can use the formula:

Time = (Thickness)^2 / (4 x Diffusion Coefficient)

Given that the steak is 4 cm thick, we can substitute the values into the formula:

Time = (4 cm)^2 / (4 x Diffusion Coefficient)

To find the answer, we need to know the diffusion coefficient for the marinade. Without this information, we cannot determine the exact time for marinading the steak. Therefore, the correct answer would be insufficient information provided.
