The tea was no longer hot or (brewed) so the 5th didn’t dissolve like the others because the tea was hot or warm enough anymore it cooled down. So the sugar won’t dissolve no more.
Explanation:
Balloon that an ocean diver takes to a pressure of 202 k Pa will get reduced in size that is the volume of the balloon will get reduced. This is because pressure and volume of the gas are inversely related to each other.
According to Boyle's law: The pressure of the gas is inversely proportional to the volume occupied by the gas at constant temperature(in Kelvins).
(At constant temperature)
The pressure beneath the sea is 202 kPa and the atmospheric pressure is 101.3 kPa . This increase in pressure will result in decrease in volume occupied by the gas inside the balloon with decrease in size of a balloon. Hence, the size of the balloon will get reduced at 202 kPa (under sea).
Answer: if doing it on ck-12 the answer is 40.1
Explanation:
Answer:
<em><u>Glass that will sink</u></em>
- 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
<em><u>Glass that will float</u></em>
- 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
<em><u>Glass that will not sink or float</u></em>
- 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:
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.
<em><u>Glass that will sink</u></em>
- 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.
<u><em>Glass that will float</em></u>
- 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.
<em><u>Glass that will not sink or float</u></em>
- 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
