Explanation:

Answer 2

Answer:

A. On a hot day, air molecules have more energy

Explanation:

The molecules in air are affected by temperature. The air molecules are always moving; however, their movement depends upon the hotness and coldness of the environment. When the day is hot, the temperature is high and this allows the molecules to increase their kinetic energy. This makes choice A correct.

On the contrary, when the day is cold, the temperature decreases and this prevents the molecules from moving so much. This means their kinetic energy decreases. This makes choice B incorrect.

Nitrogen is always abundant on the Earth's atmosphere, so this makes choice C incorrect. Take note that molecules are constantly moving, thus choice D is incorrect.

WILL MARK BRAINIEST Read the excerpt from "Everest Then and Now."Most climbers train a lot before attempting to climb Everest. They train to improve their physical condition. The most common ways to train include climbing, swimming, running, biking, and weightlifting. You need to have good endurance, stamina, and strength to climb Everest. They also need to buy equipment, including boots and clothes made of special materials. Spikes that attach to boots are necessary to prevent slipping. Having an ice ax also makes climbing easier. Ski goggles protect the eyes from high winds and blowing snow in blizzards. Portable burners and lightweight pots are needed for cooking on the mountain. An outdoor GPS receiver is also necessary so that climbers can be located if they get stuck and need to be rescued. There is an area of the mountain called Khumbu Icefall. This area contains shifting ice and deep crevasses. Special ropes and ladders are needed to cross this area. Climbers use the ladders and ropes to build bridges across gaps in the snow and ice. Some climbers bring their laptops, phones, and cameras to document their journey to the peak. Believe it or not, Everest has a Wi-Fi network.What other information would help explain why special equipment and training is important?A. Information about how climbers feel when they are stuck in an unpredictable situation while climbingB. Information about the color and style of the clothing that climbers who are fashionable wearC.
