When water freezes it forms a lattice pattern and ______
nirvana33 [79]
When water freezes it forms a lattice pattern and expands. Because the water forms a crystal lattice when frozen, it's volume increases because the water molecules take up a lot of space but they aren't very compact.

Two identical containers, one red and one yellow, are inflated with different gases at the same volume and pressure. Both contai
Evgen [1.6K]

Answer:

8

Explanation:

Here we're dealing with the root mean square velocity of gases. We'll provide the formula in order to calculate the root mean square velocity of a gas:

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

Here:

R = 8.314 \frac{J}{K mol} is the ideal gas law constant;

T is the absolute temperature in K;

M is the molar mass of a compound in kg/mol.

We know that the gas from the red container is 4 times faster, as it takes 4 times as long for the yellow container to leak out, this means:

\frac{v_{rms, red}}{v_{rms, yellow}} = 4

We also know that the temperature of the red container is twice as large:

\frac{T_{red}}{T_{yellow}} = 2

Write the ratio of the velocities and substitute the variables:

\frac{v_{rms, red}}{v_{rms, yellow}}=\frac{\sqrt{\frac{3RT_{red}}{M_{red}}}}{\sqrt{\frac{3RT_{yellow}}{M_{yellow}}}}=4

Then:

\frac{\sqrt{\frac{3RT_{red}}{M_{red}}}}{\sqrt{\frac{3RT_{yellow}}{M_{yellow}}}}=\sqrt{\frac{3RT_{red}}{M_{red}}\cdot \frac{M_{yellow}}{3RT_{yellow}}}=\sqrt{\frac{T_{red}}{T_{yellow}}\cdot \frac{M_{yellow}}{M_{red}}}=4

From here:

16 = \frac{T_{red}}{T_{yellow}}\cdot \frac{M_{yellow}}{M_{red}}

Then:

\frac{M_{yellow}}{M_{red}} = \frac{16}{\frac{T_{red}}{T_{yellow}}} = \frac{16}{2} = 8
