The color of a star is primarily determined by its surface temperature.
For example, the really hot stars, called White Dwarf stars, have a white surface temperature, while a cooler star would have a more red color.
plastic items take up to 1000 years to decompose in landfills. But plastic bags we use in our everyday life take 10-20 years to decompose, while plastic bottles take 450 years.

Solution A has 10 times more hydrogen ions than solution B.. The correct option is B.
<h3>What is a pH?</h3>
pH is the potential of hydrogen ions, or measure of hydrogen ion concentration.
It is generally used to determine the acidity and basicity of the solution based on pH scale.
The pH scale is logarithmic, which means that each pH unit contains ten times the number of hydrogen ions as the unit above it. So solution A has 10 times more hydrogen ions than solution B.
Thus, the correct option is B.
