How does temperature effect density and the flow of convection currents?
Answer:
Convection
Explanation:
Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks.

When are zeros significant when found in front of (to the left) of the decimal point?
Answer:
If a zero is found between important digits, it is important. Zeros are also used as (not salient) holders to the left of digits if the number is in fact a decimal. Example from www.rpi.edu: , a mass of 42 g has two significant digits. Expressed in kilograms, the mass of 0.042kg should still have two significant digits.

How does cold water affect the speed of dissolving?
A. Cold water slows down dissolving
B. Cold water speeds up dissolving
C. Cold water has no effect on dissolving
D. Cold water completely stops dissolving
Answer:
Cold water slows down dissolving
Cold water slows down dissolving. Hence, option (A) is correct.
What is the relationship between the solubility and the temperature?The basic relationship between solubility and temperature is as follows: A solid will dissolve more readily at higher temperatures.
Likewise, a solid element dissolves more slowly at lower temperatures. This is all due to the solvent becoming more and more excited by the heat, making it easier for it to split or break apart entirely.
for while in gases The solubility of gases decreases more rapidly as temperature rises. A gas is more soluble in water when the temperature is lower.
Henry's law, which states that the gas becomes more soluble as the pressure above the liquid solution increases, summarizes another characteristic of gas solutes.
