Two solid blocks are allowed to cool in a laboratory. Their measurements are shown in the table.
| Block | Material | Mass in kg | Specific heat capacity in J/kg °C | Temperature at start in °C | Temperature at end in °C | Cooling time in min |
|---|---|---|---|---|---|---|
| P | Copper | 0.40 | 385 | 90 | 60 | 7.0 |
| Q | Aluminium | 0.50 | 900 | 80 | 62 | 5.0 |
Calculate the ratio of the mean rate of energy loss for block P to that for block Q.
