Explanation:
N-n : 167 (energy) 145 (length)
N=n : 418 (energy) 125(length)
N (three lines)n : 942 (energy) (110) length
(not sure if I’m too late but I asked my teacher and she looked at the answer sheet so it’s correct )
Answer:
The big energy change when water freezes is in the potential energy of interactions between the water molecules.
Explanation:
I am not to sure if this is correct, but I hope it helps in some way.
Answer:
25.2°C
Explanation:
Given parameters:
Energy applied to the water = 1000J
Mass of water = 50g
Final temperature = 30°C
Unknown:
Initial temperature = ?
Solution:
To solve this problem, we use the expression below:
H = m c Ф
H is the energy absorbed
m is the mass
c is the specific heat capacity
Ф is the change in temperature
1000 = 50 x 4.184 x (30 - initial temperature )
1000 = 209.2(30 - initial temperature)
4.78 = 30 - initial temperature
4.78 - 30 = - initial temperature
Initial temperature = 25.2°C
Answer:
I believe the answer is compressed
Explanation:
The answer may be a slightly different word, but if it's looked at by a human and not a robot compressed should work too
