Explanation: Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor (Dunn,1993).
When silver is poured into the mould the it will solidify
In this process the phase of the Silver block will change from liquid to solid.
This phase change will lead to release in heat and this heat is known as latent heat of fusion.
The formula to find the latent heat of fusion is given as

here given that


now we can find the heat released


So it will release total heat of 55.5 kJ when it will solidify
D is your answer hope this helps
Geologists do not use a minerals color or streak to identify them because some minerals can have the same streak and color but the correct answer is
b) color
Answer:

Explanation:
In that the gas thermometer is a constant volume, it is satisfied that:
How the boiling water is under regular atmospheric pressure, then

Thus
