the second answer its science behind it
It’s pretty simple actually anything that moves has energy say you threw a ball u transferd your kinetic energy into that ball it’s really simple anything that moves has energy
Answer:
Final temperature of water is 
Explanation:
1 mol of LiBr releases 48.83 kJ of heat upon dissolution in water.
So, 2 moles of LiBr release
or 97.66 kJ of heat upon dissolution in water.
This amount of heat is consumed by 1000.0 g of water. Hence temperature of water will increase.
Let's say final temperature of water is
.
So, change in temperature (
) of water is
or (t-25) K
Heat capacity (C) of water is 
Hence, 
where m is mass
So, 
or, 
Hence final temperature of water is
