| Response | N(%) | Response | N(%) | |
| R1 | The temperature of water is lowered and the temperature of icepack is increased | 5 (5.2) | As the temperature rises⋯ | 1 (1.1) |
| R2 | Two (water & icepack) temperatures will be similar. | 10 (10.4) | Volume increases | 1 (1.1) |
| R3 | Not applicable | They (joints) will get narrowed and fit together | 2 (2.2) | |
| R1-R2-⋯ | The temperature of the water will decrease and the temperature of the ice pack will increase (R1-Ma) so that the temperature will be similar (R2-Ma). | 18 (18.8) | The particles become active (R1-Mi) and become bulky (R2-Ma)⋯. and the gap is narrowed (R3-Ma). | 8 (8.8) |
