What types of rock make up the continental crust?
zlopas [31]

There are two types of rocks that make up the continental crust "sedimentary and metamorphic rocks." Sedimentary rocks are formed with pressure and compaction, and metamorphic rocks are made with heat and pressure. The earth's crust itself is made up of sedimentary rocks because they are mainly found a little under earths crust same goes with metamorphic rocks.

Hope this helps!

A chamber with a fixed volume is shown above. The temperature of the gas inside the chamber before heating is 25.2 C and it’s pr
rusak2 [61]

Answer:

Explanation:

Given parameters:

Initial temperature T₁  = 25.2°C  = 25.2 + 273  = 298.2K

Initial pressure  = P₁  = 0.6atm

Final temperature = 72.4°C   = 72.4 + 273  = 345.4K

Unknown:

Final pressure = ?

Solution:

To solve this problem, we use an adaption of the combined gas law where the volume gas is fixed. This simplification results into:

                  \frac{P_{1} }{T_{1} }   = \frac{P_{2} }{T_{2} }

where P and T are temperatures, 1 and 2 are initial and final temperatures.

 Input the parameters and solve;

          \frac{0.6}{298.2}   = \frac{P_{2} }{345.4}  

          P₂   = 0.7atm
