Answer: The three main rock types are igneous, metamorphic and sedimentary.
The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation.
Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
Explanation:
Ideal Gas Law
Given: P1= 1.25 atm P2= 95 atm
V1= 2.50 L
Unknown: V2=?
Formula: V=nRT/P; n = RT / PV
Solution: n = (0.0821 L x atm / K x mol) (285K) / (1.25 atm) ( 2.50L)
= 23.40 / 3.125
Answer: n = 7.49 moles of gas the balloon holds
