Question

15. When a cola bottle or can is opened a 'fizz is observed. The fizz is the escaping of the
dioxide from the cola, What does this help us to understand about the behavior of gazes?

A. Gases dissolve better at high temperatures,
B. Gases dissolve worse at high pressures,
C. Gases dissolve better at high pressures,
D. Gases react chemically with cola water,​

Answer 1

Answer:

According to the question

l think it is Option C

Answer 2

When a cola bottle or can is opened a 'fizz is observed. The fizz is the escaping of the carbon dioxide from the cola, this helps us to understand the behavior of gases that C. Gases dissolve better at high pressures.

Impact of pressure on gas dissolution:

• When would be expected, as pressure rises, gases become more soluble.
• According to Henry's Law, a gas's solubility in a liquid is inversely correlated with its pressure above the solution's surface. thus this will most effectively release the exerted pressure.
• With less pressure, fewer gas molecules are dissolved in the solution, allowing for a greater presence of gas molecules in the air.
• Gas is very soluble when at high pressure.
• Temperature and pressure are the two direct variables that impact solubility.
• Pressure solely influences the solubility of gases, but temperature affects the solubility of both solids and gases.
