The universe is everything. It contains billions of galaxies.
A galaxy, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core. Most galaxies have a supermassive black hole at their centres.
Then the sun smallest.
Answer:
a). is lower in elevation than city B
Explanation:
Temperature of a place greatly varies with height or altitudes.
As we go higher the atmospheric pressure becomes less and the temperature decreases. We feel cold at higher altitude places and relatively hot at places of lower elevation. Therefore City A which is at lower elevation has greater annual temperature range than the temperature range of city B although they are located at the same latitude. City A is at lower altitude and City B's elevation is higher. So City A has higher temperature range than city b.
Answer:

Explanation:
Let assume that air behaves ideally. The equation of state of ideal gases is:

Where:
- Pressure, in kPa.
- Volume, in m³.
- Quantity of moles, in kmol.
- Ideal gas constant, in
.
- Temperature, in K.
Since there is no changes in pressure or the quantity of moles, the following relationship between initial and final volumes and temperatures is built:

The final temperature is:
