Final Glass

AI Thread Summary

The discussion focuses on calculating the final temperature of tea after pouring it into a glass cup. The initial conditions are 0.22 liters of tea at 95 degrees Celsius and a 150-gram glass cup at 25 degrees Celsius. A user attempted to solve the equation 0.21(95-T) = 150(25+T) but realized the need to correctly use 0.22 instead of 0.21. The correct approach involves setting up the heat transfer equation properly to find the final temperature. Accurate calculations are essential for determining the final temperature in this scenario.

If 0.22L of tea at 95 degrees C, is poured into a 150g glass cup initially at 25 degrees C, what will the final temperature be, assuming no heat is lost to the surroundings?

What have you tried?

I tried the following:
0.21(95-T) = 150(25+T)

and then solved for T but it did not work out

its actually 0.22 and 0.21

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 '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}...
