Temperature change of ice water

AI Thread Summary
To determine the final temperature of the watermelon submerged in icy water, the energy exchange must be analyzed using the equation Q = mcT, where c represents the specific heat capacity of water. The energy lost by the watermelon as it cools down will equal the energy gained by the water as it warms up. Given that the watermelon weighs 25 pounds and starts at 29.4 degrees C, while the water is at 0 degrees C, the setup involves calculating the heat transfer between the two. The problem emphasizes the importance of setting up the equations correctly rather than simply providing the answer. Understanding the principles of energy conservation is key to solving this type of thermal equilibrium problem.

A tub of icy water at 0 degrees C hold 100 gallons. You put a 25 pound watermelon with a temperature of 29.4 degrees C. The tub is wrapped in blankets to avoid heat loss. What will be the final temperature of the watermelon, considering that a watermelon is mostly water?

Would you like to make some sort of attempt at the answer?
 
I am attempting to help my nephew with the problem but I can't remember how to go about setting up a problem like this, I don't need the answer, just some help on setting it up.
 
Sorry - there is a homework forum which puts up a template to fill in what you have done so far. There is no point in us just supplying answers to homework questions

There is an equation linking the amount of energy to the temperature change
Q = mcT, where c is the specific heat capacity of water

The energy lost by the watermelon = the energy gained by the water.
 

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}...
