Answer:
The final temperature of water = 22.1224 °C
Explanation:
<u>Step 1</u> : defien the formula for heat transfer
q = m*c*ΔT
with q = heat transfer
with m = mass of the substance
with c = specific heat ( of water in this case)
with ΔT = difference between final temperature and initial temperature
In this case :
q=366kJ = 366 *10^3 J
mass of water = 48kg = 48000g
c= specific heat of wwater = 4.184 J / g °C
initial temperature = 20.3 °C
final temperature = TO BE DETERMINED
<u>Step 2</u>: Calculate temperature
366000 J = 48000g * 4.184J/g °C * (T2 - 20.3)
366000 / (480000 * 4.184) = 1.8224 = (T2 - 20.3)
T2 = 20.3 + 1.82 =22.1224 ° C
The final temperature of water = 22.1224 °C
Atoms are electrically neutral because the number of protons, which carry a 1+ charge, in the nucleus of an atom is equal to the number of electrons, which carry a 1- charge, in the atom. The result is that the total positive charge of the protons cancels out the total negative charge of the electrons so that the net charge of the atom is zero. Most atoms, however, can either gain or lose electrons; when they do so, the number of electrons becomes different from the number of protons in the nucleus. The resulting charged species is called an ion.
Answer:
A variable is anything that can change or be changed. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment.
