Answer : The final temperature of the mixture is 
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
And as we know that,
Mass = Density × Volume
Thus, the formula becomes,
where,
= 
= specific heat of water = same
= 
= mass of water = same
= 
= density of water = 1.0 g/mL
= volume of water at 
= 
= volume of water at 
= 
= final temperature of mixture = ?
= initial temperature of water =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final temperature of the mixture is
Answer:
<u>Oxygen</u>
Explanation:
If we had the same question then the table would've given the specific heat for these gases:
Water (steam) | 2.08
Air (25°C) | 1.01
Oxygen | 0.92
Hydrogen | 14.30
Out of these options, oxygen has the lowest specific heat and so it has the least heat-storing ability of the group.
We can change a gas to a liquid by INCREASING the temperature and DECREASING the pressure
