Question

Which list has the best ideas and explanations to conserve electricity in a hot environment?
A.
Idea Explanation
white exterior walls The color white absorbs less sunlight, so less light will be transformed into heat energy.
small windows Small windows let natural light diffract around corners to light the home.
dull shingle roof Dull surfaces refract light, so less light will be transformed into heat energy.

B.
Idea Explanation
black exterior walls The color black refracts less sunlight, so less light will be transformed into heat energy.
large windows Large windows let natural light refract around corners to light the home.
shiny metal roof Shiny surfaces diffract light, so less light will be transformed into heat energy.

C.
Idea Explanation
white exterior walls The color white absorbs less sunlight, so less light will be transformed into heat energy.
large windows Large windows let natural light diffract around corners to light the home.
shiny metal roof Shiny surfaces reflect light, so less light will be transformed into heat energy.

D.
Idea Explanation
black exterior walls The color black reflects less sunlight, so less light will be transformed into heat energy.
small windows Small windows let natural light reflect around corners to light the home.
dull shingle roof Dull surfaces absorb light, so less light will be transformed into heat energy.

Answer 1

The best list that presents effective ideas and explanations to conserve electricity in a hot environment is **C**.

Here's why:

1. **White exterior walls**: The explanation is correct that white surfaces reflect more sunlight, meaning less is absorbed and transformed into heat energy. This helps maintain cooler indoor temperatures.

2. **Large windows**: While the explanation is misleading (it suggests driving natural light around corners, which isn't accurate), large windows can be beneficial for natural ventilation if positioned correctly, allowing for better airflow that can cool a space.

3. **Shiny metal roof**: The explanation accurately states that shiny surfaces reflect light, reducing heat absorption, which is beneficial for keeping the building cooler in hot environments.

The other lists contain incorrect details in their explanations or suggest strategies that would not effectively conserve electricity in heat.
