A practical pursuit of alchemy was the development of metallurgy practices. As alchemists always tried to turn various metals into other things, metalworking techniques were developed even though their experiments were often unsuccessful.

Answer:
1.47 atm
Explanation:
Step 1: Given data
- Initial volume (V₁): 32.4 L
- Initial pressure (P₁): 1 atm (standard pressure)
- Initial temperature (T₁): 273 K (standard temperature)
- Final volume (V₂): 28.4 L
- Final temperature (T₂): 352 K
Step 2: Calculate the final pressure of the gas
We can calculate the final pressure of the gas using the combined gas law.
P₁ × V₁ / T₁ = P₂ × V₂ / T₂
P₂ = P₁ × V₁ × T₂ / T₁ × V₂
P₂ = 1 atm × 32.4 L × 352 K / 273 K × 28.4 L = 1.47 atm
Answer:
C₂ = 0.0712
Explanation:
Given data:
Pressure 1 = 795 torr
Solubility = 0.0356
Pressure 2 = 1590 torr
Solubility = ?
Solution;
Pressure and solubility are both directly proportional to each other.
P₁/C₁ = P₂/C₂
795 /0.0356 = 1590 / C₂
C₂ = 1590 × 0.0356 / 795
C₂ = 56.604 /795
C₂ = 0.0712
Answer:
A. The Earth rotates on its axis over 24 hours.
Explanation:
Day and night. The Earth is a sphere, or ball, which spins round and round as it travels around the sun. ... Because the Earth is constantly spinning, the line between day and night is always moving around the planet. A day on Earth lasts 24 hours—that is how long it takes for the planet to spin around once.
