Heat Exchange in Mixtures & Thermodynamics

AI Thread Summary
Heat exchange in mixtures and thermodynamics involves understanding how energy is transferred during phase changes, such as melting and vaporization. The process requires specific amounts of heat energy, known as latent heat, which does not affect temperature but facilitates the breaking of molecular bonds. For instance, converting 2.0 kg of ice at 0°C to water at 0°C requires latent heat of fusion, while changing 500 g of water at 100°C to steam at 100°C involves latent heat of vaporization. These concepts are crucial for calculating energy requirements in thermal processes. Understanding these principles can enhance knowledge of heat transfer in various mixtures.

i would like to know more about the heat exchange in mixtures and thermodynamics
example would be like:

How much heat energy is required to change?
a) 2.0kg of ice at 0 C to water at 0 C?

b) 500g of water at 100 C to steam at 100 C?

These change of state transitions are the result of molecules having sufficient energy to overcome bonds with other water molecules. This bond-breaking heat energy does not increase temperature (ie molecular kinetic energy) and is called latent heat (of fusion / vaporization). Just look up these latent heats to find the heat energy involved in each of these examples.

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...
