Answer: Option (a) is the correct answer.
Explanation:
Specific heat is defined as the heat energy necessary to raise the temperature of a 1 kg of substance by one degree celsius.
For example, specific heat of water is 4.18 J
Whereas heat of vaporization is the energy absorbed at a certain temperature to convert a unit mass of a substance from liquid to vapor state.
Hence, we can conclude that Sascha is observing the property that water has a high specific heat capacity.
Answer:
1000 times.
Explanation:
Hello,
In this case, since the pH is defined by:
If we want to compute the concentration of hydrogen we must write:
Thus, for both the backyard soils we compute:
It means that:
It means that the concentration of hydrogen at a pH of 4 is 1000 times greater than the concentration of hydrogen at a pH of 7.
Regards.
