Answer: 39.0 g</h2>
Explanation:
Mass = volume × density
⇒ mass of iron = (5 cm³ ) (7.8 g/cm³)
= 39.0 g

Answer:
Because most of the human body (about 70% of it) consists of water
Explanation:
The main reason why the specific heat capacity of the human body is very close to that of water is that water makes approximately 70% of the substances of which the human body consists. However, the human body has a slightly smaller specific heat capacity than water, because it contains also other elements/substances, and since water is one of the substances with the higher specific heat capacity at all, the specific heat capacity of the body is a bit smaller.
