AI Thread Summary
The discussion focuses on calculating the density of nitrogen gas at different temperatures and pressures. Given the initial conditions of 273 K and 1.013 x 10^5 Pa, the density is 1.25 kg/m3. Using the ideal gas law, the density at 330 K and 1.40 x 10^5 Pa is determined to be 1.43 kg/m3. The calculations confirm the density increase due to the higher pressure and temperature. The final result is verified as accurate.

Homework Statement


In temperature 273 kelvin and pressure 1.013*10^5 Pa, the density of nitrogen is 1,25 kg/m3. Find the density of this gas in temperature 330 kelvin and pressure 1.40*10^5 Pa.

T1=273 K; p1=1.013*10^5Pa; d1=1.25 kg/m3

T2=330 K; p2 =1.4*10^5 Pa. d2=?

Homework Equations


p1V1/T1=p2V2/T2

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}...
