Incresing Pressure will increases the amount of gas dissolved !!
so your answer is B !!
Extra : Cool example is Pepsi or coke !! CO2 is dissolved by high pressure
Answer: 
Explanation:
Multiply by t on both sides.
Now divide by I to isolate t.
Answer:D molecular attraction increases as temp decreases
Explanation:A,B would require data not available. C is missing. The question is a mess.
The buoyancy of an object is dictated by its density. So let us calculate for density, where:density = mass / volume
Calculate the volume first of a solid cube:volume = (6 cm)^3 = 216 cm^3 = 216 mL
Therefore density is:density = 270 g / 216 mLdensity = 1.25 g / mL
Therefore this object will float in the layer in which the density is more than 1.25 g / mL.
