Tar is thick and viscous, so it doesn't flow easily like other liquids. This is why it needs to be heated or diluted in order to become more fluid and easier to pour or work with. Heating tar reduces its viscosity, making it less sticky and more pourable.
When tar is hard to pour because it doesn't flow easily, it is called high viscosity. This means that the tar has a thick consistency, making it difficult to pour or manipulate.
Highly viscous tar, such as road tar or cold-applied tar, can be hard to pour because it has a thick and sticky consistency that does not flow easily. This type of tar requires additional heating or agitation to make it more fluid and easier to work with.
Tar is hard to pour because it is a highly viscous material, meaning it has a thick and sticky consistency that resists flowing easily. This high viscosity is due to its molecular structure and composition, making it difficult to pour and manipulate compared to more fluid substances.
Because a solid has a fixed shape while a liquid has no fixed shape. However, it is possible to pour dry sand and that IS a solid. Can you think of why that is
Warm honey has lower viscosity than cold honey, meaning it flows more easily. When honey is warmed, the molecules have more energy and move around more freely, causing them to flow more readily. Cold honey has higher viscosity because the molecules are more tightly packed and less able to move past each other easily.

Viscous fluids are difficult to pour or flow easily because they have high resistance to deformation and flow. This resistance is due to the strong intermolecular forces present in viscous fluids, which make it harder for the molecules to move past each other. As a result, viscous fluids flow slowly and require more force to pour compared to less viscous fluids.

Tar is harder to pour because their are more particles in a smaller quatity of liquid.Think of this: just like tar particles, its harder to get threough a mall that is packed than one that is empty.
It is a liquid because flows easily and can pour easily.
At a defined temperature a liquid become semisolid and doesn't easily flow: this is the pour point. This is important to establish the temperature range in which this material can be used.
At a defined temperature a lubricant become semisolid and doesn't easily flow: this is the pour point. This is important to establish the temperature range in which this lubricant can be used.
You can pour sand, salt, and sugar because they are dry granular substances that flow easily due to their small particle size and lack of cohesive forces between the particles. This allows them to move and settle into containers or be poured out without sticking together.

It is difficult to pour water from a narrow necked bottle because the narrow opening restricts the flow of the water, causing it to pour out slowly. Additionally, air is unable to flow into the bottle quickly enough to replace the exiting water, creating a vacuum effect that further hinders the pouring process.
One can describe how a liquid pours by its viscosity. Viscosity is a liquid's ability to resist flow. Therefore, the higher the viscosity, the "thicker" the liquid is and causes it to pour out slowly. If a liquid is said to have a low viscosity, the liquid is "thinner" and can easily be poured out.
