Question

What system should you avoid if you want to permit construction in poor weather?

1) Open system
2) Closed system
3) Hybrid system
4) None of the above

Answer 1

If you want to permit construction in poor weather, you should avoid an open system, as it allows both energy and matter to be exchanged with the environment, which can cause disruptions. Closed systems are more suitable as they only allow energy exchange, providing a more controlled setting for construction.

Step-by-step explanation:

When considering construction in poor weather conditions, you should avoid an open system. In an open system, the environment can exchange both energy and matter with the system, which can be problematic during poor weather as it may interfere with construction activities. For example, a car is typically considered a closed system in terms of passenger compartment being sealed from the environment, while a spring-operated dart gun is an open system to some extent as it exchanges energy with its surroundings.

A closed system, on the other hand, allows for energy but not matter to be exchanged with the environment, which tends to be more controlled and therefore more suitable for construction during adverse weather conditions. A hybrid system could be partially open and closed and may offer some protection against the weather, but it would not be as secure as a fully closed system. Choosing such a system for construction could result in delays or damage due to exposure to the elements.
