A biome is a large area characterized by its vegetation, soil, climate, and wildlife. ... Marine biomes cover close to three-quarters of Earth's surface. Marine biomes include the ocean, coral reefs, and estuaries. Grasslands are open regions that are dominated by grass and have a warm, dry climate.

1. When the Kelvin temperature of an enclosed gas doubles, the particles of the gas ____. (1 point)

My name is Ann [436]

Answer 1 : The correct option is, move faster

Explanation :

As we know that the kinetic energy of the particle of the gas is directly proportional to the temperature of the gas. That means higher the temperature higher will be the kinetic energy.

When the Kelvin temperature of an enclosed gas doubles, the kinetic energy will be double and then the particles of the gas move faster.

Answer 2 : The correct option is, It increases by a factor of eight.

Explanation :

According to the Boyle's law, the volume of the gas is inversely proportional to the pressure of the gas at constant temperature and the number of moles of gas.

$\frac{P_{final}}{P_{initial}}=\frac{V_{initial}}{V_{final}}$

$\frac{P_{final}}{P_{initial}}=\frac{4L}{0.5L}=8$

Hence, the gas pressure change increases by a factor of eight.

Answer 3 : The correct option is, the volume of a gas is directly proportional to its temperature in kelvins.

According to the Charles's law, the volume of the gas is directly proportional to the temperature of the gas at constant pressure and the number of moles of gas.

$V\propto T$

$\frac{V}{T}=k$

Answer 4 : The correct option is, 36 ml

Solution : Given,

initial volume = 17 ml

initial temperature = $-112^oC=273+(-112)=161K$

final temperature = $70^oC=273+70=343K$

Formula used : $\frac{V_{final}}{V_{initial}}=\frac{T_{final}}{T_{initial}}$

$\frac{V_{final}}{17ml}=\frac{343K}{161K}$

$V_{final}=36ml$

Therefore, the volume of the sample occupy at $70^oC$ is, 36 ml

Answer 5 : The correct option is, temperature, pressure, and volume

Explanation :

Combined gas law is the combination of the Boyle's law, Charles's law and Gay Lussac's law at constant number of moles of gas.

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

The variable used in the combined gas law are temperature, pressure, and volume .
