Answer 1

Gold.

Step-by-step explanation:

The specific heat is the measure to determine which material needs a lesser amount of energy to rise its temperature. Specific heats are described below:

Aluminium:
`903\,(J)/(kg\cdot ^(\circ)C)`

Gold :
`129\,(J)/(kg\cdot ^(\circ)C)`

Water:
`4184\,(J)/(kg\cdot ^(\circ)C)`

Wood:
`1300\,(J)/(kg\cdot ^(\circ)C)`

Gold reports the lowest specific heat and, hence, requires the least energy to raise its temperature 7°C.
