Arely Whitehead · Answer 1

Option A = copper

Explanation:

According to specific heat capacity of substances, copper will reach to the our body temperature first.

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m * c * ΔT

specific heat capacity of copper = 0.385 J/g. °C

specific heat capacity of aluminium = 0.902 J/g. °C

so copper will absorb the heat very quickly and raise the temperature in very less time as compare to aluminium.
