I don't know about 14, but 15 is (4), because a liquid draws in heat to turn into a gas. 16 is (2), because to turn into a cold solid, something has to release heat.
Answer:
Yes, given statement is true.
Explanation:
Given that a cylinder of 1000 ml is marked at every 100 ml.
During the test, the student can easily check the volume of liquid so the student's guess is 750 ml true.
With this measurement, we can estimate that 1/10th of 100 ml can be measured.
So, given statement is correct.
Answer: The given statement is true.
Explanation:
It is known that due to increase in temperature ice melts. Therefore, during ice age there is also melting of ice and solid state of water changes into liquid state of water.
Therefore, this water moves from its initial place and changes its position result in the change of land and specific areas.
Thus, we can conclude that the statement during an ice age, land can move and specific areas can be permanently changed is true.
Answer:
56.0 g
Explanation:
Calculation of the moles of 
as:-
Mass = 85.0 g
Molar mass of = 162.2 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction:-
1 mole of on reaction forms 1 mole of 
Also,
0.52404 mole of on reaction forms 0.52404 mole of
Moles of = 0.52404 moles
Molar mass of = 106.867 g/mol
Mass = Moles*Molar mass = 
= 56.0 g
