You take a bottle of soft drink out of your refrigerator. The contents are liquid and stay liquid, even when you shake them. Pre
inna [77]

Answer:

The correct answer is due to the difference in pressure inside and outside the bottle.

Explanation:

Liquids have melting and boiling points that depend on pressure and temperature. The pressure inside the bottle is higher than the pressure outside. This causes the melting point to drop, making the liquid freeze at a lower temperature than if it were at atmospheric pressure, and therefore has a lower temperature than it would freeze at atmospheric pressure. When the bottle is uncovered, the liquid becomes an atmospheric pressure, and due to the temperature acquired when the bottle was closed the liquid freezes.

Have a nice day!

Licemer1 [7]

Answer:

              Percentage error  =  1.88 %

Solution:

Data Given:

                 Mass of Sample  =  20.46 g

                 Volume of Sample  =  43.0 mL - 40.0 mL  =  3.0 mL

Formula Used:

                 Density  =  Mass / Volume

Putting values,

                 Density  =  20.46 g /  3.0 mL

                 Density  =  6.82 g.mL⁻¹

Percentage Error:

                 Experimental Value  =  6.82 g.mL⁻¹

                 Accepted Value  =  6.95 g.mL⁻¹

                 = 6.82 g.mL⁻¹ / 6.95 g.mL⁻¹ × 100  =  98.12 %

                 Percentage Error  =  100 % - 98.12 %

                Percentage error  =  1.88 %
