Answer:- The right choice is A. 
.
Solution:- Latent heat of fusion means the heat required to melt the solid at constant temperature means there is no change in temperature only the solid changes to liquid. So, it is a solid to liquid phase change.
where q is the heat required to convert solid to liquid, m is the mass and 
is the latent heat of fusion.
From given info, 550 kJ that is 550000 J of heat is required to melt 14 kg of solid at 262K temperature. Let's rearrange the equation for latent heat of fusion and plug in the values in it.
= 
If we round this value to two sig figs and write in scientific notations then it becomes .
So, the right choice is A. .
Answer:
Una partícula subatómica es aquella que es más pequeña que el átomo. Puede ser una partícula elemental o una compuesta, a su vez, por otras partículas, como los quarks que componen los protones y los neutrones. ... De esta manera, se han descubierto docenas de partículas subatómicas, y se teorizan cientos de otras más.
The correct answer is D:
it involves breaking molecular bonds between copper compounds
.
The explanation :
-when we melt a copper it is a physical change because the substance is still copper and have the same shape.
- but for example Burning a copper it is a chemical change. Fire activates a chemical reaction between copper and oxygen.
-The oxygen in the air reacts with the copper and the chemical bonds are broken.
- the chemical change is changing the other compound bonded to the copper atoms.
So, the correct answer is D
