What volume is equivalent to 12.0 m^3?

Which materials are typically used as thermal insulators? Check all that apply.

vaieri [72.5K]

Answer : The correct options are, (B) Foam, (C) Ceramic, (D) Wood and (E) Plastic

Explanation :

As we know that the conductor is the material that conduct or transmits the energy or electricity through them and insulator is the material that resist the energy transfer.

There are different types of insulators and conductors which are:

Electrical conductor : It is a type of material that conducts electrons, protons and ions. It conduct electricity. For example : silver, gold, copper, steel, brass, etc.

Thermal conductor : It is a type of material that conducts heat. For example: diamond, silver, gold, etc.

Electrical insulator : It is a type of material in which the electrical charges do not flow freely that means very little amount of electric current flow through them. For example : glass, plastic, rubber, porcelain, pure water, dry paper, dry wood, etc.

Thermal insulator : It is a type of material that reduces the transfer of heat between the object in thermal contact. For example : polystyrene foam, water, wool, plastic, ceramic, wood.

Hence, the materials typically used as thermal insulators are, foam, ceramic, wood and plastic.

What distinguishes a mixture from an impure substance?

Leno4ka [110]

Answer: Mixture can be separated into its components but impure substance cannot be separated into components.

Explanation:

A mixture is defined as a combination of two or more different substances in which the component substances are individually distinct. The substances can be separated by physical processes. The separation dos not involve any chemical process because no new substance is being formed.

Impure substance is defined as a substance which can be mixture of elements, compounds or elements and compounds. The substances cannot be separated by physical means but can only be separated by chemical means.

A gas with a volume of 8 L at a temperature of 473K is switched to a new container with a temperature of 350K. If the pressure r

Digiron [165]

Answer:

The new volume is 5.92 L, which is approximately 6 L

Explanation:

As the gas temperature increases, the molecules move faster and take less time to reach the walls of the container. This means that the number of crashes per unit of time will be greater. That is, there will be an increase (for an instant) in the pressure inside the container and the volume will increase.

So Charles's Law is one of the gas laws that relates the volume and temperature of a certain amount of gas at constant pressure and says that:
