The correct answer is option A, that is, a solution with a pH of 1.
pH refers to the unit of measure utilized to articulate the extent of acidity of a substance. The pH scale varies from 0 to 14. A pH of 0 means a very high acid activity, the hydrochloric acid, and nitric acid are very strong with pH values of 0, while the stomach acid exhibits a pH of 1.
Technically, the scale of pH, in reality, depicts the amount of positively charged H+ ions and negatively charged OH- ions in a solution. The pH scale is a logarithmic one, that is, each unit of pH exhibits 10 times as more ions of hydrogens in comparison to the unit above it.
Therefore, in a solution of pH 1, there are 10^9 times more hydrogen ions in comparison to the solution at pH 10.

According to Koppen climate classification system, humid tropical climates do not experience winter. The koppen climate classification system uses mean monthly and annual values of precipitation and temperature to classify a climate. The humid tropical climate classification has a mean temperature of above 18 degrees Celsius and the precipitation can be more than 200 cm/year. This climate does not experience winter.
Answer:
Surface area of the cube = 6cm²
Volume of the cube = 1cm³
Explanation:
The surface area of a cube, which refers to the sum of all the areas of the faces of the cube can be calculated using the formula:
S.A = 6 × a²
That is; a² + a² + a² + a² + a² + a²
Where;
a = length of a side of a cube
a² = area of one side of a cube
Note that, a cube has 6 faces
According to this question, a cube has a length of 1cm on each side.
Hence, S.A = 6 × 1²
S.A = 6 × 1
S.A = 6cm²
Volume of the cube can be calculated using the formula: a³
Where a = 1
Volume = 1 × 1 × 1
Volume = 1cm³
