Steam (water vapor) at 100 degrees celsius is added to a thermally insulated container with 200 kg of ice at zero degrees celsius. the final mixture is water at 30 degrees celsius. what was the initial mass of the steam?

Answer : The initial mass of the steam is 94.42 kg.

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 water vapor =

= specific heat of solid water =

= mass of steam = ?

= mass of solid water = 200 kg = 200000 g

= final temperature of water =

= initial temperature of water vapor =

= initial temperature of solid water =

Now put all the given values in the above formula, we get

Therefore, the initial mass of the steam is 94.42 kg.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
