Cool air from the ground floor can reach the upper floor through a process called convection. As the cool air near the ground is denser than the warm air, it naturally sinks and displaces the warm air, which rises. This creates a natural circulation of air, allowing the cool air to move upwards and reach the upper floor. Additionally, using fans or opening windows on the ground floor can help facilitate the movement of cool air to the upper floor. **

On the other hand, the Huawei Mate 20 Pro offers a larger battery capacity and expandable storage options. Additionally, the Mate 20 Pro has a higher resolution display and supports reverse wireless charging. Ultimately, the decision between the two will depend on the user's priorities in terms of camera quality, battery life, and other features. **

Circulating air can make a space feel 20 degrees cooler because it helps to distribute the air more evenly, preventing hot spots and promoting evaporation of sweat from the skin. When air is stagnant, the heat from our bodies can create a warm and uncomfortable environment. However, when air is circulated, it helps to carry away the heat and moisture, making the space feel significantly cooler. Additionally, circulating air can also help to disperse any trapped hot air and bring in cooler air from outside, further contributing to the cooling effect. **

To bring the cold air from the air conditioning on the ground floor upstairs, you can use a fan to help circulate the cool air. Placing a fan at the bottom of the stairs facing upwards can help push the cold air upstairs. Additionally, keeping doors open between the ground floor and upstairs can help facilitate the flow of air. It's also important to ensure that the upstairs area is well-insulated to prevent the cold air from escaping. **

For general use such as web browsing, email, and word processing, the MacBook Air with 8GB of RAM would be sufficient.

Ultimately, the amount of RAM you need depends on your specific usage and budget. **
