Density is the measure of how much mass is contained in a given volume.
The simplest ratios compare only two values, but ratios comparing three or more values are also possible. In any situations in which two or more distinct numbers or quantities are being compared, ratios are applicable. By describing quantities in relation to each other, they explain how chemical formulas can be duplicated or recipes in the kitchen expanded.

Angles do not change they can only rotate in a circular motion if the angles in a 30°−60°−90° triangle after it is rotated clockwise at 45°.
<h3>What are the angles?</h3>
The angles are the distance between two lines that are attached at one point and they can vary in shapes like triangle and square or circle and rectangle.
The square has the handle of equality for all the sides rectangle has two opposite side angles equal and the circle It has only one angle triangle consisting of 3 angles which are fixed and cannot be changed.
Therefore, if the angles in a 30°−60°−90° triangle after it is rotated clockwise at 45°Angles do not change they can only rotate in a circular motion.

Answer:
The answer to your question is Q = 640.5 J
Explanation:
Data
Volume of water = 15 ml
density of water = 1 g/ml
Temperature 1 = T1 = 25°C
Temperature 2= T2 = 35.2°C
Specific heat = 4.186 J/g°C
Process
1.- Calculate the mass of water
Mass = density x volume
= 1 x 15
= 15 g
2.- Substitution
Q = mC(T2 - T1)
Q = 15(4.186)(35.2 - 25)
-Simplification
Q = 15(4.186)(10.2)
-Result
Q = 640.5 J
