Four metal blocks are heated so that each undergoes the same temperature change. The table shows the mass of each block and the thermal energy transferred to it.
| Block | Mass / g\text{g}g | Energy transferred / J\text{J}J |
|---|---|---|
| 1 | 120 | 5400 |
| 2 | 200 | 12000 |
| 3 | 250 | 11250 |
| 4 | 300 | 15000 |
Which two blocks are made of the same metal?
1 and 2
1 and 3
