It became thicker and its viscosity decreased and cannot flow as easily as before.
You ignite a chemical reaction by adding the borax solution to the glue mixture.
In a chemical reaction, the molecules of glue and borax combine to form a flexible, springy new substance. With rubber's vulcanization serving as a model, chemical cross-linking has been extensively employed to change the physical properties of polymeric materials.
Chemical links between polymer chains provide a substance with a more solid structure and perhaps a better-defined shape. It thickened and lost viscosity, making it more difficult to flow than it once could.

The grand canyon is 884 m deep
<h3>Formula for velocity of echo</h3>
The velocity of an echo can be obtained by using the following formula
v = 2x / t
Where
- v is the velocity
- x is the distance
- t is the time
With the above formula, we can determine how depth the grand canyon. Details below:
<h3>How to determine the depth of the grand canyaon</h3>
- Velocity (v) = 340 m/s
- Time (t) = 5.2 s
- Depth (x) =?
v = 2x / t
340 = 2x / 5.2
Cross multiply
2x = 340 × 5.2
2x = 1768
Divide both sides by 2
x = 1768 / 2
x = 884 m
Thus, the grand canyon is 884 m deep

Answer:
A tundra has a lower average temperatures year-round.
Answer:
<u><em>No</em></u>, changes in matter are <em><u>physical changes</u></em>.
Explanation:
Answer:
The eccentricity of the ellipse is 0.252.
Explanation:
The eccentricity of an ellipse (), dimensionless, can be determined by means of the following expression:
(1)
Where:
- Distance between the foci, dimensionless.
- Length of the major axis, dimensionless.
If we know that and , then the eccentricity of the ellipse is:
The eccentricity of the ellipse is 0.252.
