A sample of nitrogen gas has a volume of 5.0 ml at a pressure of 1.50 atm. what is the pressure exerted by the gas if the volume increases to 30.0 ml, at constant temperature is 0.25atm.
On constant temperature, the pressure and volume relation become constant before and after the change in quantitities have occurred.
According to Boyle's Law,
P₁V₁ = P₂V₂
where, P₁ is pressure exerted by the gas initially
V₁ is the volume of gas initially
P₂ is pressure exerted by the gas finally
V₂ is the volume of gas finally
Given,
P₁ = 1.5 atm
V₁ = 5 ml
V₂ = 30 ml
P₂ =?
On substituting the given values in the above equation:
P₁V₁ = P₂V₂
1.5 atm × 5 ml = P₂ × 30 ml
P₂ = 0.25 atm
Hence, pressure exerted by the gas is 0.25atm.

C. Melt 1g if solid into liquid.
If they are connected exactly as shown, nothing can happen.
Answer:
Its D
Explanation:
The lamp and the ice bag were at the same place.
Sounds like the experiment was intended to show on a small scale ocean currents from the poles to the equator and back to the poles. The bag of ice would simulate the cold at the poles while the lamp would simulate the heat provided by the sun near the equator. With that in mind, let's look at the possible flaws and see what is likely.
Not enough ink was added
Since Arthur has developed a hypothesis and now is designing a study to test it, the answer which can provide the best guidance regarding his choice of measures, types of data to be collected, and methods for interpreting the data is the scientific literature in his area of interest.
Books and other research can help Arthur a lot when it comes to testing his hypothesis, because perhaps there have been other similar experiments that may aid him in putting his to the test.
