In an experiment, equal amounts of water and soil were first heated and then left to cool. The graph shows the change in tempera

ture for each with time.
A graph with the title Change in Temperature is shown. The y axis title is Temperature in degree C and the x axis title is Time in seconds. An inverted U shaped curve labeled A is plotted. A flatter curved line labeled B is also shown plotted on the graph.

Which statement about the curves A and B is true?

Curve A represents how soil takes longer to heat and longer to cool.
Curve B represents how water takes longer to heat and longer to cool.
Curve A represents water as it heats rapidly and cools slowly.
Curve B represents soil as it heats slowly and cools rapidly.

A 10-liter container has 2 moles of oxygen at a pressure of 92 kpa. The effective speed (rms) of the oxygen molecules in the gas
bezimeni [28]

The effective speed (rms) of the oxygen gas is 293.68 m/s.

<h3></h3><h3>What is Root-mean-square velocity?</h3>

Root mean square velocity is the square root of the mean of squares of the velocity of individual gas molecules

v_{rms}=\sqrt[]{\frac{3RT}{M} }

<em>where </em>R = universal gas constant

M = molar mass of the gas in kg/mol

T = temperature in Kelvin

According to the ideal gas law,

PV = nRT

RT = \frac{PV}{n}

Substitute in the rms velocity formula,

v_{rms} = \sqrt[]{\frac{3PV}{nM} }

P = 92 kPa, V = 10 L, n = 2 moles and M = 32 x 10⁻³ kg/mol

v_{rms} = \sqrt[]{\frac{3\times92\times10}{2\times32\times10^-^3} }

=293.68 m/s

Thus, the effective speed (rms) of O₂ gas is 293.68 m/s.
