A heat sink transfers energy away from a computer processor. The table shows the properties of four possible base plates. Each base plate has the same area.
| Base plate | Thickness | Thermal conductivity |
|---|---|---|
| J | 2 mm | Low |
| K | 2 mm | High |
| L | 5 mm | High |
| M | 5 mm | Low |
Which base plate will give the highest rate of energy transfer by conduction away from the processor?
Base plate J
Base plate K
Base plate L
Base plate M
