Air is heated from 50 F to 200 F in a rigid container with a heat transfer of 500 Btu. Assume that the air behaves as an ideal g
marissa [1.9K]

Answer:

V=68.86ft^3

Explanation:

T_1 =10°C,T_2 =93.33°C

Q=500 btu=527.58 KJ

P_1= 2atm

If we assume that air is ideal gas   PV=mRT, ΔU=mC_v(T_2-T_1)

Actually this is closed system so work will be zero.

Now fro first law

Q=ΔU=mC_v(T_2-T_1)+W

⇒Q=mC_v(T_2-T_1)

527.58 =m\times 0.71(200-50)

m=4.9kg

 PV=mRT

200V=4.9\times 0.287\times (10+273)

V=1.95m^3                (V=1m^3=35.31ft^3)              

V=68.86ft^3

Write a function which multiplies the values in odd position values by 10. Odd positions in this case refers to the first value
xxMikexx [17]

Answer:

Using linkedlist on C++, we have the program below.

Explanation:

#include<iostream>

#include<cstdlib>

using namespace std;

//structure of linked list

struct linkedList

{

  int data;

  struct linkedList *next;

};

//print linked list

void printList(struct linkedList *head)

{

  linkedList *t=head;

 

  while(t!=NULL)

  {

      cout<<t->data;

      if(t->next!=NULL)

      cout<<" -> ";

     

      t=t->next;

  }

}

//insert newnode at head of linked List

struct linkedList* insert(struct linkedList *head,int data)

{

  linkedList *newnode=new linkedList;

  newnode->data=data;

  newnode->next=NULL;

 

  if(head==NULL)

  head=newnode;

  else

  {

      struct linkedList *temp=head;

      while(temp->next!=NULL)

      temp=temp->next;

     

      temp->next=newnode;

     

      }

  return head;

}

void multiplyOddPosition(struct linkedList *head)

{

  struct linkedList *temp=head;

  while(temp!=NULL)

  {

      temp->data = temp->data*10; //multiply values at odd position by 10

      temp = temp->next;

      //skip odd position values

      if(temp!= NULL)

      temp = temp->next;

  }

}

int main()

{

  int n,data;

  linkedList *head=NULL;

 

// create linked list

  head=insert(head,20);

  head=insert(head,5);

  head=insert(head,11);

  head=insert(head,17);

  head=insert(head,23);

  head=insert(head,12);

  head=insert(head,4);

  head=insert(head,21);    

 

  cout<<"\nLinked List : ";

  printList(head); //print list

 

  multiplyOddPosition(head);

  cout<<"\nLinked List After Multiply by 10 at odd position : ";

  printList(head); //print list

 

  return 0;

}
