Explanation:
The given statement is true.
As per an estimate, to convert graphite into diamond nearly 1 billion to 3.3 billion years of time is required.
Graphite converts into diamond when high-pressure is applied deep in the earth core.
Lava is your answer.
Lava is molten rock that is spewed from a volcano when in eruption. Once cooled and hardened (usually through long periods of time or with contact to large bodies of water), the lava would harden and mix with other materials, allowing it to form into igneous rocks.

Answer:
1.2 °C
Step-by-step explanation:
The formula relating the heat (q) absorbed by an object, the mass (m), and the temperature change (ΔT) is
q = mCΔT Divide both sides by mC
ΔT = q/(mC)
<em>Data:
</em>
q = 15 J
m = 3.0 g
C = 4.184 J·°C⁻¹g⁻¹
<em>Calculation:
</em>
ΔT = 15/(3.0 × 4.184)
ΔT = 15/12.6
ΔT = 1.2 °C
