Which substances are difficult to classify as solids and liqurds?
Substances like gels, pastes, and colloids are often difficult to classify strictly as solids or liquids because they exhibit properties of both phases. For example, a gel can maintain a shape like a solid while also having a fluid-like consistency. Similarly, materials such as non-Newtonian fluids, which change viscosity under stress, blur the lines between solid and liquid states. These complex behaviors make categorization challenging.
Are solids gases and liquids substances?
Yes, all are substances.
How can shape and volume classify materials?
- solids have a shape and a volume- liquids have a volume but not a shape- gases haven't shape or volume (in free form)
Why are microwave spectra difficult to be observed in case of solids and liquids?
Microwave spectra are difficult to observe in solids and liquids because these materials have broad spectral lines due to molecular motion, rotation, and interactions that are faster and more complex than in gases. This results in overlapping and obscured peaks in the spectrum, making interpretation challenging. Additionally, the high dielectric constant of solids and liquids can also lead to signal attenuation and distortions in the microwave spectra.
Why can objects move through liquids but not solids?
Objects can move through liquids because the particles in liquids are loosely packed and can flow past one another. In contrast, the particles in solids are tightly packed and arranged in a fixed structure, making it difficult for objects to move through them.

How mixtures form?
mixtures can be formed by physically putting two or more substances together. Mixtures can be formed between solids and liquids, solids and solids, liquids and liquids, solids and gas, liquids and gas, gas and gas
Are substances made of particles?
there are lots of substances made up of particles, solids, liquids, gas etc.
Why is it harder to determine the relative masses of solids and liquids?
These determinations are not difficult.
What temperature do liquids turns into solids?
That temperature is known as the melting point. It is different for every substances.
What type of substances does conduction best work on?
Substances that are in form of solids offer the best conductivity compared to liquids and gases. The conduction may be sound, electricity or magnetism.
What substances can sound waves pass through?
Sound waves can pass through solids, liquids, and gases. The speed and efficiency of sound transmission can vary between different substances, with solids generally transmitting sound waves more effectively than liquids or gases.
What is meant by flammable substances?
Flammable substances are those gases, liquids and solids that will ignite and continue to burn in air if exposed to a source of ignition.
How can shape and volume classify materials?
- solids have a shape and a volume- liquids have a volume but not a shape- gases haven't shape or volume (in free form)
What can form a mixture?
A mixture is formed from substances which doesn't react.
Which state of matter cannot be compressed?
Solids and liquids are difficult compress. Gases, however, are easy; they respond to changes in temperature and volume.
