How much time does sugar takes to dissolve in : 1: ice cold water 2: room temperature 3: boiling point

2 answers:

8 0

Hey
the higher the temperature, faster will sugar dissolve so sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

If 9.5 atms of pressure were increased to 25 atms of pressure, what would be the final volume

nordsb [41]

Answer:

The final volume of the gas is 36.1 L.

Explanation:

Given:

Initial pressure of the gas is, $P_1=9.5\ atm$

Final pressure of the gas is, $P_2=25\ atm$

Initial volume of the gas is, $V_1=95\ L$

Final volume of the gas is, $V_2=?$

Here, we shall use Boyle's Law which states that for a process under constant temperature, the pressure of the gas changes inversely with the change in volume.

Here, the pressure is increased. So, the volume of the gas is decreased.

Therefore, as per Boyle's Law:

$P_1V_1=P_2V_2\\9.5\times 95=25V_2\\902.5=25V_2\\V_2=\frac{902.5}{25}\\V_2=36.1\ L$

So, the final volume of the gas is 36.1 L.
