Crystalline solids
1. The internal arrangement of particles is well defined. The molecules are lined up in a very particular order.
<span>2. They possess sharp melting points. </span>
3.<span> NaCl and NaF are examples of Crystalline solids.
</span>
<span>Amorphous solids </span>
1- The internal arrangement of particles is not well defined. Molecules are not in a particular arrangement. There is no regularity in their form.
<span>2. </span><span>They do not possess sharp melting points. </span>
3. Glass, rubber and plastics are examples of Amorphous solids..
Answer:
it will take that explosin 15.34 millisecond
Explanation:
as the speed is 767 and distance is 50 so time will be 767/50=15.34milliseconds
Answer:
Heat, Q = 45 J
Explanation:
We have,
Mass of aluminium is 5 g
The temperature is raised from 22°C to 32°C.
The specific heat of aluminium is 0.90 J/g°C.
It is required to find the heat are needed to raise the temperature.
The heat required to raise the temperature is given by :
So, 45 J of heat are needed to the temperature of 5.0 g of aluminum from 22°C to 32°C.
Both sides of the equation would be equal.
