Answer:
A flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum. The color of flames in general also depends on temperature; see flame color.

Answer:
d = 9.5× 10⁻⁴ Kg/cm³
Explanation:
Given data:
Length of cube = 1.02 cm
Mass of cube = 0.001012 Kg
Density of cube = ?
Solution:
The length , height and width of cube is always same. Thus the volume of cube is,
Volume = length × height× width
Volume = 1.02 cm × 1.02 cm × 1.02 cm
Volume = 1.06 cm³
Density of cube:
d = 0.001012 Kg /1.06 cm³
d = 9.5× 10⁻⁴ Kg/cm³
Heres the answer to the rest of that paper as well
Answer: Rotary, Oscillating, Reciprocating.
Oscillating creates pressure on the walls of the container
Explanation: Molecules are colliding with each other and with the wall of the inside of the container bouncing back and forth in oscillating motion. As they collide, they exert force and fill the container. Hence the Oscillating motion creates pressure from swinging of molecules from wall to wall.
