Question

in which story is the answer to the question 0?
naomi took an ice pack out of the freezer to cool down after her morning run. when she took it out of the freezer, the temperature of the ice pack was -18°c. after holding on to the ice pack for an hour, the temperature rose to 18°c. how much warmer is the ice pack now than it was when naomi took it out of the freezer?
naomi took an ice pack out of the freezer to cool down after her morning run. when she took it out of the freezer, the temperature of the ice pack was -18°c. after holding on to the ice pack for an hour, the temperature rose 18°c. what is the temperature of the ice pack now?

Explanation:

Step1: Calculate temperature change in first - story

To find how much warmer the ice - pack is, we subtract the initial temperature from the final temperature. Initial temperature $T_1=- 18^{\circ}C$, final temperature $T_2 = 18^{\circ}C$. The change $\Delta T=T_2 - T_1=18-(-18)=18 + 18=36^{\circ}C$.

Step2: Calculate current temperature in second - story

Initial temperature $T_1=-18^{\circ}C$, temperature rise $\Delta T = 18^{\circ}C$. The current temperature $T=T_1+\Delta T=-18 + 18=0^{\circ}C$.

Answer:

The second story.
