Answer:
480 mL
Explanation:
Ideal gas law states:
PV = nRT
At constant pressure, nR/P is constant. Therefore:
V / T = V / T
420 mL / 220 K = V / 250 K
V ≈ 480 mL
Answer:
Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. ... Sound travels about four times faster and farther in water than it does in air
