D. Water

Gold.

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:

Gold :

Water:

Wood:

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

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
