    Law Thermodynamics
AI Thread Summary
The first law of thermodynamics, which states that energy cannot be created or destroyed, is fundamental in various everyday applications, particularly in thermodynamic devices like steam engines. In these systems, the heat energy entering the engine minus the heat energy leaving it equals the work performed by the engine. This principle is crucial for understanding energy efficiency and conservation in mechanical systems. Additionally, it applies to everyday phenomena such as heating and cooling processes in homes and vehicles. Overall, the first law of thermodynamics is essential for analyzing energy transformations in practical applications.

The first law of thermodynamics, like any law of physics (eg. Newton's laws of motion) is simply a statement of how nature behaves.

The first law of thermodynamics is followed in the operation of any thermodynamic device, such as a steam engine. In one complete cycle, the flow of heat into the engine minus the heat flow out of the engine is equal to the work done by the engine.

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}...
