1 kg of melting ice and 1 kg of boiling water are mixed

Click For Summary

Homework Help Overview

The problem involves mixing 1 kg of melting ice and 1 kg of boiling water, with the goal of determining the final temperature of the mixture once all the ice has melted. The context is centered around thermodynamics and heat transfer principles.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss assumptions regarding the initial temperatures of the ice and water, with some suggesting the need for additional information such as the latent heat of fusion. There is uncertainty about the final temperature, with one participant speculating a value of 50°C.

Discussion Status

The discussion is ongoing, with participants exploring different assumptions and questioning the adequacy of the information provided. Some guidance has been offered regarding the initial conditions, but no consensus has been reached on the final temperature or the necessary calculations.

Contextual Notes

Participants note the importance of considering latent heat and the specific conditions under which the mixing occurs, such as atmospheric pressure. There is an acknowledgment that more information may be required to arrive at a definitive answer.

1. 1 kg of melting ice and 1 kg of boiling water are mixed: Which temperature will have the mixture when all ice is liquefied ?



I don't know if there is formula



The attempt solution: I don't know this question is really hard there are not enough information

I would start by assuming atmospheric pressure, also assuming the ice is at 0°C and boiling water is at 100°C.

mmm 50C ? i don't know :(
 


From my perspective, I would think that you need more information to accurately answer this question. Such as the latent heat of fusion of ice for one.
 


I agree with Taxonfear... solid ice at 0 centigrade has to change into water at 0 centigrade
Then water at 0 centigrade has to be heated to the final temp. All of the energy to do this comes from water at 100 centigrade
