What are the changes you observed in the body color and perspiration level in response to?
In response to exercise, the body color may appear flushed due to increased blood flow and circulation. Perspiration levels will typically increase as the body works to cool itself down through sweat evaporation. Additionally, the skin may feel warmer to the touch as the body's temperature rises during exercise.

What is the liquid in a mood ring that changes?
A mood ring is a ring which contains a thermochromic element, such as liquid crystal. The ring changes color in response to the body temperature of its wearer. The color is said, by some proponents, to indicate the emothional state of the wearer.
What is it called when a substance changes color in response to pH?
This is a pH indicator.
Are temperature or color changes always observed at the same time as the formation of gas bubbles?
Temperature or color changes are not always observed simultaneously with the formation of gas bubbles. The occurrence of these changes depends on the specific chemical reaction taking place. In some reactions, gas formation may happen without any noticeable temperature or color change, while in others, these changes can be pronounced. Therefore, while they can be related, they do not always occur together.
What is the name of the chemical that changes colour in acids and bases?
The chemical that changes color in acids and bases is called an indicator. Common indicators include litmus, phenolphthalein, and bromothymol blue. These substances change color in response to pH changes in a solution.
What do you call a substance which is used to show changes in pH by its change in color?
An indicator. It is a substance that changes color in response to a change in pH, making it a useful tool in chemistry to visually determine the acidity or basicity of a solution.

Why there is no color changes in iodometric titration?
In iodometric titration, color changes may not be observed because the iodine produced does not have a distinctive color, especially when combined with starch as an indicator. Instead, the end point is typically detected by a color change from blue-black to colorless when the starch-iodine complex is reduced by the analyte.
What chemical turns yellow when sprayed with bleach?
Phenolphthalein is a chemical that turns yellow when sprayed with bleach. It changes color in response to changes in pH levels, and in the presence of bleach its color shifts from colorless to yellow.
What does universal indicator test for?
A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.
