Answer:
Option (B)
Explanation:
Felsic magma refers to those magma that are comprised of more than 65% of silica content and are highly made up lighter elements like oxygen, silicon, sodium, aluminum, potassium, and are light-colored in comparison to the basic magma. Due to its high silica content, these are high viscosity magma and flows at a much slower rate. The felsic magma crystallizes at a relatively low-temperature rocks and the rocks that are formed from this type of magma have a specific gravity of less than 3.
Thus, the correct answer is option (B).

Hey there !
<span>Convert Joule to KJ :
</span>
1 j ---------------- 0.001 kj
53.69 j ----------- Kj
Kj = 53.69 * 0.001
=> 0.05369 Kj
T = ΔH / <span>ΔS
T = 49.09 / 0.05369
T = 914.32ºC</span>
