The motion of the molecules decreases.
<u>Explanation</u>:
- Gases are formed when the energy in a system overcomes the attractive forces between the molecules. The gases expand to fill the space they occupy. In this way, the gas molecules interact little. In the gaseous state, the molecules move very quickly. As the temperature decreases, the amount of movement of the individual molecules also decreases.
- The fast-moving particle slows down. When a particle speeds up, it has more kinetic energy. When a particle slows down, it has less kinetic energy. The particles in solid form are commonly connected through electrostatic powers. They don't get enough space to move around, therefore, their speed diminishes, they can't keep their standard speed like in the vaporous or fluid state.
Answer:1:En química, el número másico o número de masa es la suma del número de protones y el número de neutrones del núcleo de un átomo. Se simboliza con la letra A (el uso de esta letra proviene de alemán Atomgewicht, que quiere decir peso atómico, aunque sean conceptos distintos que no deben confundirse).
2:

Explanation:
C. reducing the amount of garbage
Explanation:
The biggest long-term benefit of building a city's recycling building is that it helps to reduce that amount of garbage.
Recycling is simply the collection and processing of waste materials into new products that can be used again.
- Waste recycling helps to reduce that actual proportion and percentage of materials to be considered waste.
- The overall long term goal of any recycling procedure is to reduce the amount of garbage in the environment.
