Which material is more closely related to the styrofoam? a. heat exchanger b. diffuser c. insulator d. electrical conductor
nirvana33 [79]

The material that is more closely related to the Styrofoam insulator.

Styrofoam is the term that is used for polystyrene foam in a trademark form. It is a petroleum-based plastic.

Keeping something warm includes the stopping of the transfer of heat from one object to another. This is how insulation works.

Styrofoam is an insulator, which means it'll help keep the heat from the environment out of your cooler. However, you'll still need cooling agents (like ice packs) to make the cooler cold in the first place.

Styrofoam is usually made mostly of air, which means it is a poor conductor of heat, but an excellent convector. It traps the air in small pockets, which blocks the flow of heat energy. This reduces both conduction and convection and makes Styrofoam a good insulator.

A cell phone weighing 80 grams is flying through the air at 15 m/s what is the kinetic energy
hjlf

Answer:

9\:\mathrm{J}

Explanation:

Kinetic energy is given by the following equation:

KE=\frac{1}{2}mv^2, where m is mass in \mathrm{kg} and v is velocity in \mathrm{m/s}.

Since the cell phone's mass is given in grams, we need to convert this into kilograms:

80\:\mathrm{g}\cdot \frac{1\:\mathrm{kg}}{1000\:\mathrm{g}}=0.08\:\mathrm{kg}.

Therefore, the kinetic energy of the cell phone is:

KE=\frac{1}{2}\cdot 0.08\cdot 15^2=\fbox{$9\:\mathrm{J}$}.
