A diver exhales a bubble with a volume of 250 mL at a pressure of 2.4 atm and a temperature of 15 °C. What is the volume of the bubble when it reaches the surface where the pressure is 1.0 atm and the temperature is 27 °C, if the amount of gas does not change?

The final volume of the bubble = 625 ml = 0.625 L

Explanation:

= 0.25 L = 250 ml

= 2.4 atm

= 15 °c = 288 K

= 1 atm

= 27 °c = 300 K

Mass of the gas is constant.

We know that

Put all the values in above equation we get

= 625 ml = 0.625 L

This is the final volume of the bubble.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
