If its accel is constant and not changing from its number then the velocity is changing so True
Answer:
18 L
Explanation:
Use ideal gas law:
PV = nRT
Find initial number of moles, but first convert to units that match the gas constant units.
(200,000 Pa) (0.025 m³) = n (8.314 Pa m³ / mol / K) (25 + 273.15 K)
n = 2.017 mol
At the new pressure and temperature:
(250,000 Pa) V = (2.017 mol) (8.314 Pa m³ / mol / K) (0 + 273.15 K)
V = 0.018 m³
V = 18 L
Mass is a measure of the amount of matter in an object !!
hope this helpeddd (:
If a substance can not be separated physically or chemical it is an element.
