AI Thread Summary
The discussion revolves around a heat transfer problem involving a copper cup and tea reaching thermal equilibrium. The cup has a mass of 0.1 kg at an initial temperature of 20 degrees Celsius, while the tea weighs 0.2 kg and is initially at 70 degrees Celsius. The specific heat capacities for tea and copper are provided as 4180 J/kg*K and 381.6 J/kg*K, respectively. The key point is that the final temperature of the system will be the same for both the cup and the tea once thermal equilibrium is achieved. The original poster ultimately resolved the problem independently.

Heat "Q" homework

Homework Statement


A cup from copper with mass 0,1 kg, with the initial temperature 20 degrees centigrade is filled with 0,2 kg tea with temperature 70 degrees centigrade. Which is the final temperature after the tea and the cup reached the thermic balance?
c tea = 4180 J / kg * K
c Cu = 381,6 J / kg * K

Thanks a lot, 47Alexander.

If the system is in thermal equilibrium then it's final temperature must be equal. Also the heat transferred into the cup must equal what?
 


Nevermind, I solved it. Thanks anyway.

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 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
