Why does a molecule of a gas move at high speed?
It has more energy within it which speeds it up causing it to fly faster and bounce harder off of other molecules thus pushing them farther apart creating a gas.
What type of transport is used to move a molecule from a region of low concentration yo a region of high concentration?
Gas molecule always move. The movement is called Brownian Motion, a random behaviour of molecule and atom in fluid state. These little motion enhance diffusion even without any additional driving force. Gas had less interaction force than liquid and so the speed of motion is a lot greater and so higher diffusivity.
No, gas molecules move at different speeds, colliding fast molecules with slow molecules would transfer energy from the fast molecules to the slow molecules, making the slow molecule faster than it was going before. Law of Conservation of Energy: Energy cannot be created nor destroyed, only transferred
Molecules in the gas state move much faster than their liquid or solid states. Depending on the temperature and pressure, molecules can exist in three states: gas, liquid, or solid. At high temperatures and low pressures, the gas state is favored. When the molecule is in the gas state, it actually hits other molecules and bounces in random directions. A molecule moving as a gas is like a weightless baseball hit inside a big empty…
The average speed of gas molecules is typically given as the root mean squared velocity. vrms = √(3RT/M) R is the ideal gas constant (8.3145 J/mol*K), T is the Kelvin temperature, M is the mass of one mole of the gas in (kg/mol). From the equation, you can see that a high temperature results in a high RMS velocity, as does a low molar mass.
The space between the gas molecules is very large. The forces between the gas molecules are very low (vanderwalls forces) , so molecule tends to move freely with out having influence of other molecule. The gas is compressive , Less force is required to compress gas . Finally Gas can take the Shape and volume of container it occupies.
In a solid, the molecules are very close and compact with very no space to move around. In a liquid the molecules have little space to move around, and in a gas, the molecules are very spaced out. The gas molecules move around a lot because they have so much space between and around them. Hope this helped..
it gets hot and becomes gas Or the heat from the fire starts to excite the molecules in the water. These molecules then speed up as they move and start to separate. When these molecules start to move quickly and separate, they become lighter that air due to their increasing speed. The water molecules then are able to move into the air and become classified as a gas.
