0.30

Wool

1.75

Concrete

0.88

Air

1.00

Silver

0.24

Which material from the provided options is best suited for a thermal insulator due to its ability to resist temperature changes and effectively slow down heat transfer?

Question 10 options:

Styrofoam

Concrete

Air

Wool

Answer 1

The best material for a thermal insulator among the options provided is Styrofoam.

Specific heat capacity is a measure of how much heat energy is required to change the temperature of a material. A lower specific heat indicates that the material will heat up and cool down more quickly, while a higher specific heat indicates that it takes more energy (and thus time) to change the temperature of the material.

Styrofoam has a specific heat capacity of 0.30 J/g°C, which is lower compared to Wool (1.75 J/g°C), Concrete (0.88 J/g°C), and Air (1.00 J/g°C). This lower specific heat suggests that Styrofoam will resist temperature changes more effectively than the other materials, making it a better thermal insulator.

So the correct answer is Styrofoam.
