Once the chicken has reached 0ºC, you can add it to the sous-vide cooker (the Yeti cooler). What is the change in temperature (ºC) of the chicken during the sous-vide cooking process if the equilibrium temperature is 74ºC? Do not include units with your answer.

Change in temperature = 74

Explanation:

The initial Temperature of the chicken is given as 0° C. Then the question states that the chicken is added to sous-vide cooker. And the final equilibrium temperature after cooking is given as 74°C. The equilibrium temperature means that the temperature of each component in the system, such as cooker and chicken is same, which is 74°C. So, we have:

Initial Temperature = 0

Final temperature = 74

Therefore, the change in temperature during cooking will be:

Change in Temperature = Final Temperature - Initial temperature

Change in Temperature = 74 - 0

Change in temperature = 74
