Asked Sep 18, 2019

A Carnot heat engine uses a hot reservoir consisting of a large amount of boiling water and a cold reservoir consisting of a large tub of ice and water. In 5 minutes of operation of the engine, the heat rejected by the engine melts a mass of ice equal to 4.25×10^{−2} kg .

Throughout this problem use Lf=3.34×105J/kg for the heat of fusion for water.

A)

During this time, how much work W is performed by the engine?

W = ______________ J

Step 1

The mass of ice is 4.25x10^{-2}kg.

Write the expression for work done by heat engine.

Step 2

Write the expression for and .

Step 3

Substitute the values of QH and QC i...
