Answer:

Explanation:
Our values are,
State 1

We know moreover for the tables A-15 that

State 2

For tables we know at T=320K

We need to use the ideal gas equation to estimate the mass, so



Using now for the final mass:



We only need to apply a energy balance equation:




The negative value indidicates heat ransfer from the system
Answer:
//The program prompts user to input three integers and it displays them, adds and gets their average
//begin
public class Test
{
public static void Main()
{
//input intergers
int[] score = new int[3];
int avg,rem,sum = 0;
for(int i=0;i<3;i++)
{
Console.WriteLine("Enter an integer score ");
score[i] = Convert.ToInt32(Console.ReadLine());
sum = sum + score[i];
}
avg = sum/3;
rem = sum%3;
Console.WriteLine("The average of "+score[0]+","+score[1]+","+score[2]+" is "+avg +" with a remainder of "+rem);
}
}
