Answer:

  1. 1,882.8 joules
  2. 83.652 calories

Explanation:

Given:

Amount in calories = 450 calories

Amount in joules = 3.5 × 100 joules

Find:

  1. Change in joules
  2. Change in calories

Computation:

We know that,

1 calories = 4.184 joules

So,

Amount in calories = 450 calories

= 450 × 4.184

= 1,882.8 joules

Amount in joules = 3.5 × 100 joules

=  [3.5 × 100] / 4.184

= 83.652 calories

Sati [7]

Answer:

Swelling of the red blood cells occurs.

Explanation:

  • <u>Distilled water makes the blood hypotonic ,. that is a less concentrated solution, to the body  tissues including  the red blood cells. </u>
  • Therefore the water will enter the red blood cells and may cause them to lyse or swell.
  • <em>Additionally , water will enter the tissue spaces and cause sweling. </em>
  • But in the case of a hypertonic solution , ( a salt or saline solution ) , <em>This swelling does not happen because the concentration of the saline will be equal or more than the blood. </em>
  • Thus the water will flow only from the blood to the solution. <u>This will not cause swelling.</u>
  • But too much of salt is also not recommended.
