The troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea)

The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere.

The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.

Mesosphere The mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high. Meteors burn up in this layer.

Exosphere This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km

An air conditioning unit turns off once it reaches its goal temperature. The house warms up and the air conditioning unit turns
-Dominant- [34]

Answer:

D ) feedback

Explanation:

When we use an air conditioner, it get turn off when reaches its required temperature and when the house warm up the air conditioning unit turns on again, that is an example of feedback.

The given condition is an example of negative feedback because in negative feedback, any change in the input is opposed by generating an output. Here also,  warming up of house (change in one direction) allows the air conditioning unit turns  on and it gives cool air (opposing that change).

Hence, the correct option is "D".

A balloon is filled with 2.5 L of helium at 1 atm of pressure. If the pressure
ch4aika [34]

Answer:

5 L

Explanation:

Given data

  • Initial pressure (P₁): 1 atm
  • Initial volume (V₁): 2.5 L
  • Final pressure (P₂): 0.50 atm
  • Final volume (V₂): ?

For a gas, there is an inverse relationship between the pressure and the volume. Mathematically, for an ideal gas that undergoes an isothermic change, this is expressed through Boyle's law.

P_1 \times V_1 = P_2 \times V_2\\V_2 = \frac{P_1 \times V_1}{P_2} = \frac{1atm \times 2.5L}{0.50atm}= 5 L

Which of the following trends can be observed when moving down a column in the periodic table
Vlad [161]

Explanation:

A column on the periodic table represents a period.

These are some of the variations observed across a period;

  • Atomic radii decreases progressively from left to right due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.
  • Ionization energy increases progressively from left to right due to decreasing atomic radii.
  • Electronegativity increases from left to right.
  • Electropositivity decreases across a period.

Explain how you can obtain hydrated sodium sulphate crystals from an aqueous solution of sodium sulphate​
Mice21 [21]

Answer:

If you left your aqueous sodium sulfite solution open on the side, atmospheric oxygen would cause the chemical change, the water would hydrate the new compound and the slow evaporation of water would give you lovely large crystals of Na2SO4 without you having to do anything!
