There are several information's already given in the question. Based on the information's the answer can be easily deduced.

We know the formula

P1*V1/T1 = P2*V2/T2

As the temperature is constant, so T1 and T2 can be negated. The formula changes to
P1*V1 = P2*V2
70 * 1 = 540 * V2
270/540 = V2
V2 = 0.5

From the above deduction, we can conclude that the new volume is 0.5 liters. I hope that the procedure is clear enough for you to understand.

The sink-float method is often used to identify the type of glass material found at crime scenes by determining its density.

Olegator [25]

Answer:

Glass that will sink

alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density of 2.46 g/mL

potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL

Glass that will float

soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL

alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL

Glass that will not sink or float

potash borosilicate with a density of 2.16 g/mL in a solution with a density of 2.16 g/mL

Explanation:

Density is the property of matter that states the ratio of the amount of matter, its mass, to the space occupied by it, its volume.

So, the mathematical expression for the density is:

density = mass / volume

By comparing the density of a material with the density of a liquid, you will be able to determine whether object will float, sink, or do neither when immersed in the liquid.

The greater the density of an object the more it will try to sink in the liquid.

As you must have experienced many times an inflatable ball (whose density is very low) will float in water, but a stone (whose denisty is greater) will sink in water.

The flotation condition may be summarized by:

When the density of the object < density of the liquid, the object will float

When the density of the object = density of the liquid: the object will neither float nor sink

When the density of the object > density of the liquid: the object will sink.

Glass that will sink

alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density of 2.46 g/mL, because 2.57 > 2.46.

potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL, because 3.05 > 1.65.

Glass that will float

soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL, because 2.27 < 2.62.

alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL, because 2.26 < 2.34.

Glass that will not sink or float

potash borosilicate with a density of 2.16 g/mL in a solution with a density of 2.16 g/mL, because 2.16 = 2.16
