Answer:
Final temperature = 149 K
Explanation:
Given data:
Initial temperature = 25°C (25+273 = 298 K)
Initial volume = 4.5 L
Final temperature = ?
Final volume = 9.0 L
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₂ = T₁V₂/V₁
T₂ = 4.5 L × 298 K / 9.0 L
T₂ = 1341 L K / 9.0L
T₂ = 149 K
Answer:
protons only
Explanation:
proton is present in the nucleus of atom as sub atomic particle ..
proton has + charge in the it's top as p+..
Because ionic bonds form between oppositely charged particles. Opposit s attract.
If that’s not correct, give me the options and I can try to help further.
Kinetic energy=1/2*mass*velocity²
=1/2*291*49
=7129.5 Joules
Answer:
It’s to gain territory
Because they wanted more territory than what they already had.
