12.0 l of gas in a piston at a pressure of 2.00 atm are compressed until the volume is 7.00 l. what is the new pressure inside the piston?

  The  new  pressure  inside  the piston is   3.43 atm

    Calculation

The  new  pressure is calculated  using  Boyle's  law  formula

that is  P1V1= P2V2   where,

P1= 2.00 atm

V1= 12.0 L

P2=?

V2= 7.00 L

make  P2   the  subject  of the formula  by diving both side by V2

P2 =P1V1/V2

P2= (2.00 atm  x12.0 L) / 7.00L  = 3.43  atm

what's the question?

explanation:

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
