IB Physics SL B 1 7 Thermal Transfer Direction Questions

Practise IB Physics SL B.1.7 by determining thermal-energy transfer direction and explaining how systems approach equilibrium.

Exam points

Identify the temperature difference between bodies as setting the net direction of thermal-energy transfer.
Explain thermal transfer from hotter to colder regions until thermal equilibrium, using complete evidence and clear system boundaries.

[Maximum number: 3]

This question is in two parts. Part 1 is about the motion of a ship. Part 2 is about melting ice.

The whole of the experiment in (f)(i) and (f)(ii) is repeated with a container of negligible mass that is not isolated from the surroundings. The temperature of the surroundings is $18^{\circ} \mathrm{C}$ . Comment on the final temperature of the water in (f)(ii).

ice/water spends more time below $18^{\circ} \mathrm{C}$ ;
so net energy transfer is in to the system;
so final water temperature is higher;
or
ice/water spends less time below $18^{\circ} \mathrm{C}$ ;
so net energy transfer is out of the system;
so final water temperature is lower;
