C - rising and cooling, causing water vapor to condense
A and C are the correct answers. Because there is no gravity to pull fluids down, they are in your face and hands more than normal. Our bones and muscles become weaker because without gravity objects lack weight.
Answer: Option (a) is correct.
Explanation:
It is known that electrons hold a negative charge. So, when the negative charge that is electrons are taken out an atom then the number of electrons become less in number as compared to the number of protons.
Hence, the atom attains a positive charge.
An isotope is formed when an atom shows same number of protons and different number of neutrons. So, when an atom loses 2 electrons there will be no change in the number of neutrons. Therefore, an isotope will not form.
Thus, it is concluded that when an atom with no charge loses two electrons, it becomes a positive ion.
A 10.0cm3 volume of alcohol has a mass of 7.05g. 
is the density
Answer:
<u>Explanation:</u>
The ratio between the mass of a substance and its unit volume is referred as density.
is the Answer
<u>Note:</u>
1000 g = 1 kg
100 cm = 1 m
When we used to transform the given values into S.I units, then
Alcohol’s volume can be written as, 
Alcohol’s mass can denote as, 
Then,
