<span>Agre tested his hypothesis in a simple experiment where he compared cells which contained the protein in question with cells which did not have it. The trials were ran with artificial cells, liposomes, which are a type of soap bubble. He found that the liposomes became permeable if the protein was planted inside of the membrane.</span>

Oxygen can combine with a metal to produce a compound
Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.


where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron = 
= initial temperature of water = 
Now put all the given values in the above formula, we get:


Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
