Answer:
Caffeine
Explanation:
Caffeine is the world's most widely consumed additive chemical substance. But unlike other substances it is legal and not regulated under any jurisdiction
Its use has been almost doubled since 1980s. After Caffeine comes the rank of NCT a highly substance found in tobacco substances.
Answer:
a) The volume increases
b) The volume decreases
c) The volume does not change
Explanation:
<em>A gas at a pressure of 2.0 atm is in a closed container. Indicate the changes (if any) in its volume when the pressure undergoes the following changes at constant temperature and constant amount of gas.</em>
<em />
When there is a change in the pressure (P) at constant temperature (T) and amount of gas (n), we can find the change in the volume (V) using Boyle's law.
P₁.V₁ = P₂.V₂
where,
1 refer to the initial state
2 refer to the final state
<em>a) The pressure drops to 0.40 atm.</em>
P₁.V₁ = P₂.V₂
(2.0 atm) . V₁ = (0.40 atm) . V₂
V₂ = 5 . V₁
The volume increases.
<em>b) The pressure increases to 6.0 atm.</em>
P₁.V₁ = P₂.V₂
(2.0 atm) . V₁ = (6.0 atm) . V₂
V₂ = 0.33 . V₁
The volume decreases.
<em>c) The pressure remains at 2.0 atm.</em>
P₁.V₁ = P₂.V₂
(2.0 atm) . V₁ = (2.0 atm) . V₂
V₂ = V₁
The volume does not change.
Answer:
the energy of particles increase
Answer:
The work done by the mixture during the compression is W=∫V2V1pdV. With the adiabatic condition of Equation 3.7. 14, we may write p as K/Vγ, where K=p1Vγ1=p2Vγ2.
