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
