Answer:
Answer is c....115°C
Explanation:
Gay-Lussacs law says that pressure of a gas is the same as temperature when the volume is kept the same
P / T = k
where P - pressure , T - temperature in kelvin and k - constant
parameters for the first time are on the left side of the equation and parameters for the second instance are on the right side of the equation
T1 - 25 °C + 273 = 298 K
substiuting the values in the equation
T2 = 388 K
temperature in celcius - 388 K - 273 = 115 °C

For the first question:
Valuable ore deposits and gem crystals are often associated
with igneous intrusions. So for this question the correct option is option “d”.
An example like the Pegmatite’s, which are a form of igneous intrusions, is
responsible for the creation of variety of gems like topaz and tourmaline.
For the second question:
For this specific question, option “c” seems to be the
correct option. Weathering, deposition, compaction, cementation are the
possible sequence that leads to the formation of sedimentary rocks.
