Question

the table shows the same data about how the temperature of each vial of insulin changed over 15 minutes. which statement is correct? thermal energy was transferred more slowly into the vial on the counter. thermal energy was transferred more slowly into the vial in the refrigerator. thermal energy was transferred into both vials at the same rate.

Explanation:

Step1: Calculate temperature change for counter vial

The temperature change for the vial on the counter is $\Delta T_{counter}=5.7 - 2.5=3.2^{\circ}C$.

Step2: Calculate temperature change for fridge vial

The temperature change for the vial in the refrigerator is $\Delta T_{fridge}=3.9 - 2.5 = 1.4^{\circ}C$.

Step3: Compare rate of heat transfer

Since both vials are observed over the same time - interval of 15 minutes, and the vial in the refrigerator has a smaller temperature change, it means thermal energy was transferred more slowly into the vial in the refrigerator.

Answer:

Thermal energy was transferred more slowly into the vial in the refrigerator.
