Heat Energy and Power -- Heating ice in a copper pan

AI Thread Summary
To calculate the power needed to heat a 1360-gram chunk of ice in a 600-gram copper pan from 0°C to 35°C in 10 minutes, the relevant equations include Q=mcΔT for the copper and Q=mLf for the ice. The total heat energy required combines the heat absorbed by the ice as it melts and the heat absorbed by the copper as it warms up. The final state of the ice is water at 35°C, which is essential for determining the total energy needed. The power can then be calculated by dividing the total energy by the time of 10 minutes. Understanding the final state of the ice and the temperature of the entire system is crucial for accurate calculations.

Homework Statement


Calculate the power needed to heat a 1360 gram chunk of ice in a 600 gram copper pan from 0 ◦C to the system’s final temperature of 35◦C in a time of 10 minutes.

Homework Equations


Q=mcchange in temp
Q=mLf
P= energy/time

The Attempt at a Solution


I thought that adding the heat energy of ice, q=mLf, with the copper's heat, q=mc change in temp, and then dividing by time. Or would subtract copper from ice? And what do I do when it says temp of whole system?

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}...
