When colorless phenolphthalein is added, upon mixing it will turn a beautiful shade of pink. This chemical reaction occurs when a base such as ammonia is mixed with an acid like hydrochloric acid.
In a liquid, molecules are relatively close together but not as tightly packed as in a solid. The average distance between molecules in a liquid is typically about 1 to 2 nanometers, allowing them to slide past one another, which gives liquids their fluidity. This proximity enables liquids to maintain a definite volume while taking the shape of their container.
Particles in a liquid are in constant motion, moving past each other. They have more freedom to move compared to particles in a solid but are still close together, allowing liquids to take the shape of their container. This movement is what gives liquids their fluidity.
Liquid particles are always in constant motion, sliding past one another while maintaining a close proximity. This movement allows liquids to flow and take the shape of their containers. The particles vibrate and collide with each other, which gives liquids their ability to adapt to different shapes while retaining a definite volume. Additionally, the kinetic energy of these particles is influenced by temperature, affecting their speed and interactions.
A carpet is a solid. It is made up of fibers, typically woven or tufted together, which gives it a definite shape and volume. Unlike liquids and gases, solids maintain their form and do not flow to fill a container. Therefore, carpets are classified as solid materials.
Closed flash point refers to the minimum temperature at which a flammable liquid gives off sufficient vapor to form an ignitable mixture in the presence of an ignition source, under specific test conditions where the container is closed. It is an important safety parameter for handling and storing flammable liquids.
Yes, but very difficult: high pressure gives very tiny volume change
Yes, in a liquid, the particles can move past each other, allowing them to change places. This movement is what gives liquids their ability to flow and take the shape of their container.

A liquid-in-glass thermometer works based on the principle of thermal expansion. As temperature increases, the liquid inside the thermometer expands and rises in the calibrated glass tube. The level of the liquid indicates the temperature which corresponds with a specific scale on the thermometer.
Take the mass of each liquid, divide by the volume, and that gives you density. If the density is nearly 1g/mL, it is water.

Viscosity is a property of liquids and gases. In every day terms syrup is viscous and water isn't. Liquids with high viscosity are difficult to stir, there is resistance to movement through the liquid. A change of state from liquid to gas would cause the viscosity to reduce. Technically viscosity is a resistance to shear or tensile stresses. Viscosity can be measured for all liquids and gases. Wikipedia gives a technical description.

All liquids are made up of matter (atoms and molecules) which is what gives them their densities. Liquids are dense because they are made up of matter so all liquids have the same ingredient to make them dense.
Jelly is considered a liquid because it flows and takes the shape of its container, like other liquids, but it is a semisolid state due to the presence of a gelling agent like pectin, which gives it its characteristic texture.
