Specific Heat Capacity, Heat Energy, Thermodynamics Physics

AI Thread Summary
To determine the final temperature of melted water from a 150g block of ice at -4°C using 60 kJ of heat energy, the latent heat of fusion must first be calculated to melt the ice without changing temperature. Once the ice is melted, any remaining heat energy will increase the temperature of the resulting water. The specific heat capacity of water should be applied to find out how much the temperature rises after melting. It's essential to ensure that the correct physical parameters, such as the latent heat of fusion and specific heat capacity, are used in the calculations. Properly applying these concepts will yield the accurate final temperature of the water.

Homework Statement



A block of ice has a mass of 150g and a temperature of -4°. The ice is melted by supplying 60KJ heat energy. Determine the final temperature of the melted water.

Homework Equations



Equations i think can be used:

Q = ml and H = mcΔθ


The Attempt at a Solution



I have attempted the solution with even different specific heat capacities but i am getting very high temperature which does not make a lot of sense. Can you please help me out.

Have you heard of latent heat? (if they still call it that. Anyway heat of melting.)
 
yes but how to solve it using latent heat studies?
 
Well if you know what latent heat is calculate the amount of heat energy that melts that amount of ice, which is without change of temperature, then the rest of the supplied 60 kJ goes into heating the water and ice, then use specific heats to calculate how much those kJ raise the temperature. You have presumably been supplied with the relevant physical parameters to use, else you will have to find them out.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
