What is the pressure in a 24.0-LL cylinder filled with 32.7 gg of oxygen gas at a temperature of 319 KK? Express your answer to
Blizzard [7]

Answer:

The pressure in that cylinder = 1.12atm

Explanation:

We use general gas law to calculate it. General gas law is gotten by combining Boyle's law, Charles' law and Avogadro's law. Thus

P = nRT/V

Where n = number of moles

R = the gas constant

T is the Temperature, V is the volume and P is the pressure.

Given: T = 319K, V = 24L, R = 0.0821 L.atm/K.mol

The first step is to find n using

n = mass of O2/molar mass of O2

=32.7/32

=1.0219

Now, using P =nRT/V

P = 1.0219 ×0.0821×319÷24

Therefore P = 1.12atm

A weather map indicates that a low-pressure system is approaching a city. Attached to
timofeeve [1]

Answer:

The correct option is;

A warm front is approaching the city and temperatures will increase

Explanation:

A low pressure forms by the movement of air away from a particular spot such that the pressure reduces. The movement of air away from a spot occurs when there is a boundary of warm and cold air such that the air moves to maintain a uniform temperature.

Low pressure centers are associated with warm fronts, resulting in the fall of barometric pressure or observed low pressure and are characterized by a rise in temperature.
