The table shows the same data about how the temperature of each vial of insulin changed over 15minutes.

Question

Vial Initial temperature (°C) Final temperature (°C)
Vial on the counter 2.2 4.0
Vial in the refrigerator 2.2 3.0
Which statement is correct?
A.thermal energy is transferred more slowly into the viral on the counter
B. thermal energy was transferred more quickly into the violin for refrigerator
C.thermal energy is transferred into both vials at the same rate

Answer 1

To determine which statement is correct, we can analyze the temperature changes in each vial over the 15-minute period.

1. Vial on the counter:

   • Initial temperature: 2.2 °C
   • Final temperature: 4.0 °C
   • Temperature change: 4.0 °C - 2.2 °C = 1.8 °C

2. Vial in the refrigerator:

   • Initial temperature: 2.2 °C
   • Final temperature: 3.0 °C
   • Temperature change: 3.0 °C - 2.2 °C = 0.8 °C

Now, comparing the temperature changes:

• The vial on the counter experienced a greater temperature increase (1.8 °C) compared to the vial in the refrigerator (0.8 °C). This indicates that thermal energy was transferred into the vial on the counter more quickly than into the vial in the refrigerator.

Based on this analysis, the correct statement is: B. Thermal energy was transferred more quickly into the vial on the counter.
