Question

 

Water changes between solid phase (as ice) and liquid phase at 0℃. and between liquid phase and gas phase (as water vapor) at 100 ℃. Write a program to accept a temperature front keyboard, and display the corresponding water phase (solid, liquid or gas) under that temperature.

Answer 1

import java.util.*;
import java.lang.*;
import java.io.*;
import java.util.Scanner;

public class WaterState
{

public static void main (String[] args) throws java.lang.Exception

{
boolean run = true;
while(run)
{
Scanner scan = new Scanner(System.in);

System.out.println("What is the temperature in degrees Celsius?");
double temp = scan.nextDouble();
  
  
String state = "liqud";
if (temp <= 32)
state = "solid";
else if(temp >= 212)
state = "gas";

state = " Water is " + state;
  
System.out.println(state);
}

}

}
