The new temperature is 337.21 K when the pressure was reduced to 101.3 kPa from 150.2 kPa at 500 K.
Explanation:
Data given:
volume of the container = 100 ml
initial pressure on the container P1 = 150.2 kPa
Initial temperature of the container, T1 = 500 K
final temperature of the container, T2 = ?
Final pressure on the container P2 = 101.3 kPa
from the data provided, we will use Gay Lussac's law to calculate the final temperature:
rearranging the equation,
T2 =
Putting the values in the equation:
T2 =
T2 = 337.21 K
thus, the final temperature of the container is 337.21 K

The correct answer is option d, that is, colder and denser.
The surface currents refer to the currents at the surface of the water, to a few hundred meters deep, while deep currents refer to the currents when the density increases to a greater extent.
The surface current takes place close to the surface and move horizontally. This kind of currents are caused by global winds, an example of surface current is Gulf Stream. On the other hand, deep current takes place in the ocean and is affected by the density of water, temperature, and salinity. An example is Antarctica Bottom Water. In comparison to surface currents, deep currents are colder and denser.
<span>Molality(m) or molal concentration is a measure
of concentration and it refers to amount of substance in a specified amount of
mass of the solvent. Used unit for molality is mol/kg which is also
sometimes denoted as 1 molal. It is equal to the moles of solute (the substance
being dissolved) divided by the kilograms of solvent (the substance used to
dissolve).</span>
Molarity(M) or molar concentration is also a
measure of concentration and represents the amount of substance per unit volume
of solution(number of moles per litre of solution. Used unit for molarity is
mol/L or M. A solution with a concentration of 1 mol/L is equivalent to 1 molar
(1 M).
Molality is preferred when
the temperature of the solution varies, because it does not depend on
temperature, (neither number of moles of solute nor mass of solvent will be affected
by changes of temperature), while molarity changes as temperature changes(volume
of solution changes as temperature changes).
