AI Thread Summary
To calculate the number of molecules in a beach ball with a volume of 6.0*10^-2 m^3, the Ideal Gas Law is applied, which is a concept in thermodynamics. The formula used is PV = NkT, where P is pressure, V is volume, N is the number of molecules, k is the Boltzmann constant, and T is temperature in Kelvin. Rearranging the equation gives N = PV/kT. The user successfully solved the problem using this approach. This discussion highlights the application of classical physics principles in determining molecular quantities in gases.

can anyone tell me how i should approach this problem

calculate the number of molecules of air in a beach ball of volume 6.0*10^-2m^3. The air is at temperature 35degrees, a pressure of 1.1*10^5Pa and can be trested as an ideal gas.

i just want to know what area of classical physics it is

Its is Thermodynamics, and you should apply the Ideal gas law.

ehild
 
thankyou, i did manage to work it out as follows

PV=NkT

k beint the Boltzmann constant
T being temperature in Kelvins and
N = number of molecules and P and V pressure and volume

rearange N=PV/kT

simples :)
 
Good job!
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
