Answer:
Option (B) is correct.
Explanation:
Initial temperature of the gas is T.
The volume of the sample is decreased from 4.5 L to 1.5 L while the pressure is held constant.
At constant pressure, the relation between volume and temperature is given by :
Here, V₁ = 4.5 L, V₂ = 1.5 L, T₁ = T₁, T₂ = ?
So,
So, the final temperature of the gas is . Hence, the correct option is (B).
1. since Beatrice is applying force to the box, she is doing work
2. formula is work = force x displacement
3. displacement = 2 meters, force = 40 N
work = 40 x 2 = 80 Joules
I think the answer is 26,88 liters
