Assignment 1

Problem Description:

Write a program that calculates the energy needed

to heat water from an initial temperature to a final temperature. Your program

should prompt the user to enter the amount of water in kilograms and the initial

and final temperatures of the water. If water weight is negative number, the following message should be displayed: “Water amount cannot be negative number!”

The formula to compute the energy is:

result = waterWeight * (finalTemperature – initialTemperature) * 4184

Here is a sample run

Sample 1:

Enter the amount of water in kilograms: 55.5

Enter the initial temperature: 3.5

Enter the final temperature: 10.5

The energy needed is: 1625484.0

Sample 2:

Enter the amount of water in kilograms: -8

Water amount cannot be negative number!
