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
Answer: 0.43molO₂
Explanation:
The ideal gas law for moles is . If you did not know, R is the ideal gas constant,
.
Since the temperature must be in Kelvin, we must convert our given temperature from ℃ to K.
Now that we have the temperature converted to Kelvin, we can plug in our information to the ideal gas law for the number of moles.
Therefore, the number of moles is 0.43molO₂.
I hope this helps! Pls mark brainliest!! :)
