Question

You hold a gram of copper in one hand and a gram of aluminum in the other. Each metal was originally at 0° C. (Both metals are in the shape of a little ball that fits into your hand.) If they both take up heat at the same rate, which reaches your body temperature first?
a.)copper
b.)both require the same c.)energy
aluminum

Answer 1

Answer:

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.
