Answer:
hope this helps
Explanation:
answers:
1. Chemical engineering is most difficult because it's a mix of physics, chemistry and math
2. Stoichiometry is so important because it shows how materials react, interact and play off each other
3. Yes I think consumers would notice if process control standards were not met. for example medicines, when people take Tylenol or cold pills, if the amount of time it took to kick it becomes longer, people will become aware that the product is not consistent and reliable.
4. i have no idea sorry :(
5. This is explaining how there are rules and regulations to make the workplace safe. it can be accomplished by following those rules and regulations
Answer:
Explanation:
A sonic boom is a loud sound kind of like an explosion. It's caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amounts of sound energy. When an object moves through the air, it makes pressure waves in front of and behind it.
Answer:
The initial temperature will be "385.1°K" as well as final will be "128.3°K".
Explanation:
The given values are:
Helium's initial volume, v₁ = 6 m³
Mass, m = 1.5 kg
Final volume, v₂ = 2 m³
Pressure, P = 200 kPa
As we know,
Work, 
On putting the estimated values, we get
⇒ 
⇒ 
⇒ 
Now,
Gas ideal equation will be:
⇒ 
On putting the values. we get
⇒ 
⇒ 
⇒ 
(Initial temperature of helium)
and,
⇒ 
On putting the values, we get
⇒ 
⇒ 
⇒ 
(Final temperature of helium)
