Explanation:
number of grams mineral salt in one is also the description of the salinity of ocean water
Their path fluctuates to the north or south depending on the location of hot and cold air masses
Answer:exothermice
Explanation: it is relaeing heat not keeping it in
Answer:
1. Sulphuric acid
2. Car battery acid
3. Washing up liquid
4. Milk of magnesia
5. Metal polish
6. Oven cleaner
Explanation:
Universal paper can determine the pH of a solution. It ranges from dark red (pH 0 - very acidic) to orange/yellow, to green (pH 7 - neutral) to blue, dark blue and purple (pH 14 - very alkaline)
Sulphuric acid has the lowest pH as the universal indicator is red.
The next is car battery acid which is pink - not as acidic as red.
The next is washing up liquid, which is yellow, around pH 3 or 4.
The next is milk of magnesia with light blue, around pH 9 or 10.
Metal polish is dark blue - around pH 11.
Oven cleaner is the darkest, with purple.
Explanation:
Relation between pressure of water and its droplet is as follows.
where, p = pressure of droplet
= water pressure in given temperature
= 
M = Molecular Weight in Kg/Mol (0.018 for water)
r = radius in meters
= density of water in 
(1000 
)
R = ideal gas constant (8.31)
T = temperature in Kelvin
(a)
We will calculate the value of p as follows.
p = 
= 
= 26.8 torr
(b) And, vapor pressure of spherical water droplets of radius 2.0 
or 
p =
= 
= 25.2 torr
