Answer:
The correct answer is B it"s a proven fact.
Explanation:
Any scientific theory is based upon many experiments ans observations.The experiment and observations are repeated many times to provide a scientific logic about that theory.
A scientific theory is accepted only when that theory is logically proved by various experiment ,observations,statistical analysis etc.
It would be a continuous straight line

Answer:
The initial temperature was 58.4°C
Explanation:
Given the following data:
initial volume = V₁ = 380 mL = 0.38 L
final volume = V₂ = 250 mL = 0.25 L
final temperature = T₂ = -55°C = 218 K
According to Charles's law, the volume of a gas is <em>directly proportional to the temperature</em> (in Kelvin). The mathematical expression is:
V₁/T₁= V₂/T₂
So, we calculate the initial temperature (V₁) as follows:
T₁ = T₂/V₂ x V₁ = 218 K/(0.25 L) x 0.38 L = 331.36 K ≅ 331.4 K
Finally, we convert the initial temperature from K to °C:
T₁= 331.4 K - 273 = 58.4°C
Answer:
The correct answer is propane.
Explanation:
The movement of chemicals follows numerous standards, which indicate that each trailer must contain an ID number identifying the chemical being moved. This is necessary because before possible accidents and leaks we must know the measures to be taken before a leak.
Have a nice day!
