Temperature change of ice water

Click For Summary

Homework Help Overview

The problem involves a tub of icy water at 0 degrees Celsius containing a 25-pound watermelon at 29.4 degrees Celsius. The scenario is set up to explore the final temperature of the watermelon after being placed in the icy water, with considerations for heat transfer and the properties of water.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the setup of the problem, including the relevant equation for heat transfer. Some express uncertainty about how to approach the problem, while others emphasize the importance of not providing direct answers.

Discussion Status

The discussion is ongoing, with participants exploring the setup and relevant concepts. Some guidance has been offered regarding the energy balance between the watermelon and the water, but no consensus or final conclusions have been reached.

Contextual Notes

Participants note the constraints of the homework forum, which discourages direct answers and encourages a focus on understanding the problem setup and relevant equations.

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.
