Tar is a highly viscous substance that has a high molecular weight and strong intermolecular forces, making it resistant to flow easily. Additionally, tar often contains a high percentage of solid components that further hinder its flow properties.
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 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.
Tar is a conductor of electricity. This is because tar contains carbon black. Carbon though not a metal is capable of conducting electricity.
That depends how thick you like your cheese sauce! If you can pour it out on to your food it's obviously less viscous than most tars. The temperature also affects the speed at which they flow, which is why they warm up the tar in order to spread it on the road. My cheese sauce is just about able to flow when I first make it, but it usually sets when I let it go cold.
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.

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.
The statement that is true is that tar in container A (100 °C) and container B (200 °C) is at a higher temperature than the tar in containers C (50 °C) and D (25 °C). Therefore, the tar in containers A and B is likely to be less viscous and flow more easily compared to the thicker, cooler tar in containers C and D.
A solid does not flow easily.
Materials that do not allow heat to flow through easily are called insulators. Some common examples include wood, plastic, glass, and dry air. These materials have low thermal conductivity, which means they do not transfer heat efficiently.
An insulator is a material that does not allow electricity to flow easily. Some common examples of insulators include rubber, plastic, glass, and ceramic materials. These materials have high resistance to the flow of electricity, preventing current from passing through them.
"Insulator" means that electrical charge can NOT flow through it easily.
