Question

сколько времени потребуется для того,чтобы из воздушного шара объемом 540 см3 вышли все молекулы воздуха? Считайте , что каждую секунду из него выходит 10 молекул , а число молекул в 1 см3 воздуха равно 2,7*10 в семнадцотой степени

Answer 1

V = 540 см3

v = 10 млк\сек

p = 2.7 * 10^17

 

t = \$\frac{V*p}{v}$

Answer 2

Calculating the Time Required for Air Molecules to Exit the Balloon

To calculate the time required for all the molecules of air to exit a balloon with a volume of 540 cm^3, we can use the given information that 10 molecules of air exit the balloon every second and that the number of molecules in 1 cm^3 of air is 2.7*10^17.

First, we need to find the total number of molecules in the balloon. Then, we can calculate the time required for all these molecules to exit the balloon at a rate of 10 molecules per second.

Calculations

The total number of molecules in the balloon can be calculated using the given volume and the number of molecules in 1 cm^3 of air.

The total number of molecules in the balloon is given by: Total number of molecules = Volume of balloon * Number of molecules in 1 cm^3 of air

Substituting the given values: Total number of molecules = 540 cm^3 * 2.7*10^17 molecules/cm^3

Now, we can calculate the time required for all these molecules to exit the balloon at a rate of 10 molecules per second.

The time required can be calculated using the formula: Time = Total number of molecules / Rate of molecules exiting per second

Substituting the given values: Time = (540 cm^3 * 2.7*10^17 molecules/cm^3) / 10 molecules/second

Result

After performing the calculations, the time required for all the molecules to exit the balloon is approximately 1.458*10^15 seconds.

This is the estimated time required for all the molecules to exit the balloon based on the given information
