Data Given:
Pressure = P = 0.5 atm
Volume = V = 2.0 L
Temperature = T = 50 °C + 273 = 323 K
Moles = n = ?
Solution:
Let suppose the gas is acting Ideally, Then According to Ideal Gas Equation.
P V = n R T
Solving for n,
n = P V / R T
Putting Values,
n = (0.5 atm × 2.0 L) ÷ (0.0821 atm.L.mol⁻¹.K⁻¹ × 323 K)
n = 0.0377 mol
Because they insulate either the heat or the coolness within the food item. But keep in mind- when it comes to electricity aluminum isn’t an insulator.
The answer is B particles combine into a large amount of engery.
Answer:

Explanation:
Given 500 cm^3 = V1 760 mm = P1 (760*2) = P2
Required V2
P1V1 = P2V2
RE-ARRANGE TO P1V1/P2 = V2
(760)(500) /(760*2) = V2
V2 = 250 ML
