You are walking on a beach and see a split. Explain how a split could have formed from a rocky headland.
kirza4 [7]

Hello, Lindaparker, a spit  could form from a rocky headland where prevailing winds would blow at an angle to the rocky headland, gradually depositing sand and shingle at that place. A spit is a permanent land form resulting from marine deposition and wind deposition. It is usually a long and narrow accumulation of sand or shingle with one joined to the land and the other end projecting at   a narrow angle out into the sea. Salt marshes sometimes form on the sheltered side of a spit.

A 350. mL air sample collected at 35 degrees C has a pressure of 556 mm Hg.
SashulF [63]

Answer:

485 torr

Explanation:

Explanation:

We can solve this equation using the combined gas law:

P1V1/T1=P2V2/T2

Remember, always use the absolute (Kelvin) temperature when working with gas equations.

The temperature conversions are

T1=C+273=35o+273=308K

T2=57C+273=330K

Since we're trying to find the final pressure, let's rearrange this equation to solve for

P2:

P2=P1V1T2/T1V2

Our known values:

P1= 550 torr

V1=350mL

T1=308K

V2=425"mL

T2=330K

Let's plug these into the equation to find the final pressure:

The final pressure after it is subjected to these changes is thus 485torr
