Start date Feb 5, 2008

AI Thread Summary

The discussion focuses on a thermodynamics homework problem involving the compression of a gas at constant pressure. The gas is compressed from 12.00 L to 3.00 L while losing 420 J of energy as heat. Participants are tasked with calculating the work done on the gas and the change in its internal energy. Key equations related to pressure and volume changes are referenced, emphasizing the relationship between work, heat transfer, and internal energy. The conversation aims to clarify the calculations needed to solve the problem accurately.

Homework Statement

A gas is compressed at a constant pressure of 0.800 atn from 12.00 L to 3.00 L. In the process, 420 J of energy leaves the gaas by heat.

a) What is the work done on the gas?

b) what is the change in its internal energy?

Homework Equations

1atm = 1.0135e5 N/m^2
1Pa = 1 N/m^2

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...

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...
