= 5 kilogram/cubic meter
Answer: sun is directly over the equator
Explanation:
There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes.
Explanation:
It is known that the specific heat capacity of Liver
is 3.59 kJ
It is given that :
Initial temperature of Liver = Body temperature =
= 310 K
Final temperature of Liver = 180 K
Relation between heat energy, mass, and change in temperature is as follows.
Q =
Now, putting the given values into the above formula as follows.
Q = 
Q =
= 700.05 kJ
Therefore, we can conclude that amount of heat which must be removed from the liver is 700.05 kJ.
Answer:
E) molality
Explanation:
Molality -
Molarity of a substance , is the number of moles present in a Kg of solvent .
Hence , the formula for molality is given as follow -
m = n / s
m = molality
s = mass of solvent in Kg ,
n = moles of solute ,
Hence , from the given information of the question,
The concentration unit which have Kg of solvent , is molality.
