It is the s-orbital because the order of electrons is s-block, p-block, d-block, and f-block. The p, d, and I think f as well (not 100% about f though) can each hold 8 more valence electrons in their shells.

Answer:
Invasive species, runoff pollution, and climate change.
Explanation:
Invasive species, such as Burmese pythons, threaten the Florida Everglades because they are not native to the natural habitat. Pythons eat the native animals, but they don't have any predators.
Pollution from nearby farms and roads enters the water and damages the ecosystem of the Everglades and Louisiana wetlands. Toxic chemicals lead to detrimental effects for both humans and wildlife.
Humans have drained swampy areas to allow for development. However, this has led to the Everglades drying up and even burning in recent years.

Answer:
= -4.2°C
= 49.4°C
Explanation:
A Carnot cycle is known as an ideal cycle in thermodynamic. Therefore, in theory, we have:
|
| = 
Similarly,
|
| = |
| + |
|
During winter, the value of || = 20°C = 273.15 + 20 = 293.15 K and || = 1.5 kW. Therefore,
|| = 0.75( - )
Similarly,
|
| = 1 -
1.5/0.75*(293.15-) = 1 - (/293.15
Further simplification,
= -4.2°C
During summer, = 25°C = 273.15+25 = 298.15 K, and || = 1.5 kW. Therefore,
|| = 0.75( - )
Similarly,
|
| = 
- 1
1.5/0.75*( - 298.15) = (/298.15
Further simplification,
= 49.4°C
