Answer: PV = nRT
A gas at STP... This means that the temperature is 0°C and pressure is 1 atm.
R is the gas constant which is 0.08206 L*atm/(K*mol)
Rearranging for volume
V = nRT/P
The temperature and number of moles are held constant. This means that this uses Boyle's Law. (The ideal gas law could be manipulated to give us this result when T and n are held constant.)
PV = k
where k is a constant.
This means that
P₁V₁ = k = P₂V₂
P₁V₁ = P₂V₂
(1 atm) * (1 L) = (2 atm) * V₂
V₂ = 0.5 L
The new volume of the gas is 0.5 L.

Answer:
C )
Explanation:
Controlled scientific experiment tests scientific assumption (hypothesis), under controlled conditions.
In controlled scientific experiment, alters the test variable (independent variable) and observes the effects on the outcome variable (dependent variable).
Eg : Studying impact of sunlight on plant's group, where former independent variable is altered & its effects on dependent outcome variable is observed.
Soft light (answer) is the filament between (2700k-3000k).
The higher the kelvin number the whiter the light.
3500k-4100k is bright white/cool white
5000k-6500k is daylight
\and those are the three primary colors of color temperature
