Answer:
Ability to conduct electricity
Melting point
3x10^8 / (670.8 * 10^-9) =4.47x10^14 Hz 4.47x10^14 Hz multiplied by plank's constant = 2.9634x10^-19
2.96 x10-19 J
Formula
V/T = V1/T1
Givens
V = 430 L
T = - 42 °C = - 42 + 273 = 231°K
V1 = ??
T1 = 18°C + 273 = 291°K
The pressure is a constant.
Solution
420/231 = V1/291 Multiply by 291
420*291 / 231 = V1
V1 = 122220 / 231
V1 = 521.1 L
Answer:
1.79x10^-14

262. 5cm3.
using the Boyles law formula. p1v1=p2v2
P1=760torr.
v1=525cm³
p2=760×2=1520torr.
v2=?
p1v1=p2v2
760×525=1520×v2
v2=[ 760×525]÷1520
v2= 262.5cm³
when the pressure increases, the volume decreases.
