200 calories.
Explanation:
The (latent) heat of fusion of a material, is either one of:
1) the heat required to melt the material without
temperature change or
2) the heat removed from the material to freeze it
without temperature change.
For water this latent heat is 80 cal/g. Multiply this by
2.5 g to get 200 cal.
Answer:
POSITIVE DESCRIBES AN INCREASE IN SPEED AND NEGATIVE DESCRIBES A DECREASE IN SPEED.

Answer:
<h2>
32°F
/0°C
</h2>
Explanation:
At what temperature does the melting point occur?
32°F
/0°C
(32°F − 32) × 5/9 = 0°C
At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point. For most substances, the melting and freezing points are about the same temperature.
Is Melting Point affected by temperature?
Melting point, the temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
Para and ortho is actually indicating different name structure of mixture. So if structure is different then boiling/distill/melt temprature will be also different.
Answer:
It only has 7 valence electrons because there are seven electrons in the highest orbital.
