Shivering, because it’s just a reflex to maintain homeostasis and nothing is necessarily ‘coming out’
1.formular masses
2. molecular masses
3.energy and volume
4.density
Answer:
The volume of the piece of iron is 5.18dL.
Explanation:
The density (ρ) is equal to the mass (m) divided the volume (V).
If we rearrange it, we have:
To express the volume in dL we will need the following relations:
- 1 dL = 0.1 L
- 1 kg = 10³ g
- 1 cm³ = 1 mL
- 1mL = 10⁻³L
Then,
Finally,
