Answer:
449 mL
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 450 mL
V₂ = ?
P₁ = 101 kPa
P₂ = 104 kPa
T₁ = 17 ºC
T₂ = 25 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (17 + 273.15) K = 290.15 K
T₂ = (25 + 273.15) K = 298.15 K
Using above equation as:
Solving for V₂ , we get:
V₂ = 449 mL
Answer:
The one with the full load.
Explanation: We can prove this by doing V^2 X M = KE
where V= velocity M= mass and KE= kinetic energy.
is both are traveling at the same speed (let's say 2kmph) and one has a mass of 50 kg with the other having a mass of 100kg.
(plug in the values) . 2^2 X 50 = KE and 2^2 X 100= KE
(simplify) 200=KE and 400=KE
This proves that a dump truck with a larger load (if traveling at the same speed) will always contain more energy than a dump truck with a smaller load.

Agreed with guy above thanks
