Answer: The ice absorb 6671.1 kJ of thermal energy.
Explanation:
The conversions involved in this process are :
Now we have to calculate the enthalpy change.
where,
= enthalpy change = ?
m = mass of ice = 20.0 kg = 
(1kg=1000g)
n = number of moles of ice= 
= enthalpy change for fusion = 6.01 KJ/mole = 6010 J/mole
Now put all the given values in the above expression, we get
(1 kJ = 1000 J)
Therefore, the enthalpy change is, 6671.1 kJ
An object seen in the water will usually appear to be at a different depth than it actually is, due to the refraction of light rays as they travel from the water into the air. This tutorial explores how fish, observed from the bank of a pond or lake, appear to be closer to the surface than they really are.
Answer:
A. it will move faster than the large object was moving initially
The answer is the atmosphere.
Answer:
True
Explanation:
Honestly it could be true or false, but I chose true, because I do power points all the time for projects and presentations and you can add notes on the side, but they only remain visable when you go back to it. If you go to type on the power point the note will disappear.
I hope that helps
