Chapter 3: Q44E (page 576)

An ice-cube tray of negligible mass contains0.290kgof water at18.00C. How much heat must be removed to cool the water to0.000and freeze it? Express your answer in joules, calories, and Btu.

Short Answer

Expert verified

The heat released will be -1.43脳105J=-3.42脳104cal=135.5Btu.

Step by step solution

01

Stages in the process

There will be two stages in the given process, the first stage includes a decrease in the temperature of the water from 18掳Cto0掳Cwithout any change in the phase, the second stage is the change in the phase from liquid (water) to solid (ice). Hence, the amount of heat that must be removed to cool the water 0掳Cto and freeze it can be

Qremoved=mcwater螖罢-mLf

Here, the negative sign implies the removal of heat energy.

02

Use the equation to find the heat removed
