Answer:
B. 400 kPa
Explanation:
the pressure increases, when the temperature increases. and it increases, when the volume decreases.
both cases happen here, each with the factor 2.
so, the pressure increases by the factor 2×2 = 4.
4×100 = 400 kPa
Answer:
Both the Earth and Venus show the appearance of igneous rocks due to the cooling of the magma.
Explanation:
As we know, ignea rock is the first step in the transformation of rocks. This rock is formed by the overflow of terrestrial magma which, upon cooling, turns into ignea rock, which will undergo metamorphism and transform into metamorphic rock, which will continue to undergo metamorphosis until it becomes the other rocks that complete the rock cycle. This is a terrestrial process that can be found on Venus, which also presents the cooling of magma in the formation of ignea rock, which will undergo metamorphism, transforming into other rocks, the way it occurs on Earth.
Answer:
When a cold front approaches there can be a sudden drop in temperature, strong wind gusts, and heavy rain and thunderstorms.
Explanation:
Answer is: 5,1 mol KOH.
V (KOH) = 0,8l = 0,8 dm³.
c (KOH) = 6,4 mol/dm³.
V - volume of solution.
c - concentration of solution.
c = n÷V
n - amount of substance.
n (KOH) = c·V = 6,4 mol/dm³ · 0,8 dm³ = 5,12 mol.
