Which is colder a gas at -143 degrees or a gas at -245 degrees?
A gas at -245 degrees is colder than a gas at -143 degrees. Temperature is directly related to the average kinetic energy of particles in a substance, and the lower the temperature, the slower the particles are moving, making it colder.
Is scattering a natural process that keeps earths atmosphere warm?
No, scattering has nothing to do with keeping the earth warm. Scattering refers to the way rays of light, or radiation or other particles have to change direction, often when they bump into something.
Why is the temperature in the thermosphere not measured with a thermometer?
If a thermometer were placed in the thermosphere, it would register far below 0 degrees C! This may seem strange since the thermospher is so hot.(see answer to "what is one characteristic of each layer of the earth") How can this be explained? Temperatureis a measurement of how fast particles in the air move. The faster the air particles move the higher the temperature. And the particles present in the thermosphere are moving very fast. THerefore the particles themselves are very hot. But these particles are vry few and very far apart. There are not enough of them present to bombard a thermometer and warm it. So the thermometer would re3cord a temperature far below 0 degrees C.
How does the average kinetic energy of the helium atoms in a balloon change as the helium gas is heated?
As the helium gas in a balloon is heated, the average kinetic energy of the helium atoms increases. This is because an increase in temperature leads to higher molecular speeds and greater kinetic energy for the gas particles. The particles move faster, resulting in more collisions and increased kinetic energy.
Is hydrogen a ideal gas?
Hydrogen is close to an ideal gas under certain conditions, particularly at low pressure and high temperature. However, deviations from ideal behavior can occur at high pressure and low temperature due to intermolecular interactions and molecular size effects.
Which entity is measured by the movement of the gas particles in a vessel?
Temperature is measured by the movement of gas particles in a vessel. When the gas particles move faster, the temperature of the gas increases, and vice versa.
What properties of gas particles is measured by temperature?
The property of gas particles that is measured by temperature is the average kinetic energy. This energy will increase as a gas becomes warmer or the temperature increases.
Does warm air or cold air make gas particles move apart?
Gas particles, like the particles in all states of matter (solid, liquid, gas) are always moving apart and colloding with other particles. Gas particles have more space in between and tend to move faster than the particles in a solid or liquid state. Temperature only affects how fast a particle moves, therefore warm air makes gas particles move faster and cold air makes gas particles move slower.
How is the temperature of gas related to the kinetic energy of its particles?
As the temperature of a gas increases, the kinetic energy of the particles will also increase.
Can gas be cold?
Gas itself cannot have a temperature; rather, it is the particles within the gas that have kinetic energy, which determines its temperature. So, gas particles can be at a low temperature, making the gas feel cold to the touch.
What does the volume of gas depend on?
The volume of gas depends on the temperature, pressure, and number of gas particles present. These factors affect the amount of space the gas particles occupy.
A transfer of heat within a liquid or gas that involves warm particles moving in currents is what?
Convection is the transfer of heat within a liquid or gas that involves warm particles moving in currents. This process occurs due to the difference in temperature, with warmer, less dense regions rising and cooler, denser regions sinking.
What effects states of matter?
The state of matter of a substance is primarily determined by the arrangement and movement of its particles. Factors such as temperature and pressure can influence the state of matter by causing particles to move differently and form various structures, resulting in the different states - solid, liquid, and gas.
Is it true that the faster gas particles move the greater their energy and the lower their temperature?
No, the temperature of a gas is actually a measure of the average kinetic energy of its particles, not their speed. Faster-moving gas particles do have higher kinetic energy, leading to a higher temperature.
The greater the speed gas particles in a container the?
The greater the speed of gas particles in a container, the higher the overall average temperature and kinetic energy of the gas particles. And if volume was held constant, higher the pressure.
Temperature is proportional to the average kinetic energy of particles in an object thus an increase in temperature results in a?
Thermodynamic temperature (absolute temperature) is proportional to the averagekinetic energy of particles in "gases". An increase in temperature will increase theaverage kinetic energy of the particles of the gas and at the same time the particle'skinetic energy distribution gets broader.If pressure of the gas is kept constant, the gas expands (increases its volume).If the volume of the gas is kept constant, the gas pressure increases.
When the Kelvin temperature of an enclosed gas doubles the particles of the gas .?
Temperature is proportional to energy and energy of gas particles is related to their velocity via E= 1/2mv2. So if the temperature doubles then the velocity of the individual particles increases by (4dE/m)1/2 =v
