This procedure is called a throttling process or Joule–Thomson process
 
        
             
        
        
        
Answer:
6,500 gm of steam require= 3,510 kilo calories (approx)
Explanation:
Every 1 gram of water at 100° C  absorb 540 calories 
So,
Total water = 6.5 kg = 6,500 gram
So,
6,500 gm of steam require = 6,500 x 540 
6,500 gm of steam require= 3,510 kilo calories (approx)
