Question

At noon on Saturday, Rob pulled a carton of ice cream from his 30°F freezer which had been there for a week, and set it on his kitchen table, in his 75°F kitchen. He stuck a thermometer into the ice cream, and sat down to watch the thermometer. Every time the temperature of the ice cream rose 3 degrees, he wrote down the time.

Which of the following questions was Rob MOST LIKELY trying to investigate?
A.
How long can I sit and watch ice cream melt?

B.
How much ice cream melts every 10 minutes?

C.
Is ice cream heavier when it is frozen or when it is melted?

D.
How fast does ice cream go from freezer temperature to room temperature?

Answer 1

D.
How fast does ice cream go from freezer temperature to room temperature?

Answer 2

Answer:

D.  

How fast does ice cream go from freezer temperature to room temperature?

Explanation:

Here the temperature inside the freezer is 30 Degree F while temperature outside is 75 degree F.

So the ice cream must be in melt state and it will be start attaining the thermal equilibrium with surrounding temperature.

So here the temperature of ice cream will continue rise with time and it is given that Every time the temperature of the ice cream rose 3 degrees, he wrote down the time.

So as per the trend of observations we can say that the experiment here is related to

D.  

How fast does ice cream go from freezer temperature to room temperature?
