What name is used for the main type of thermal energy transfer that happens when a gas is heated?
The main type of thermal energy transfer that happens when a gas is heated is convection. In convection, the heated gas molecules become less dense and rise, while cooler gas molecules sink, creating a circular motion that transfers heat throughout the gas.
What type of energy is associated with random motion of particles in a sample of gas?
The random motion of particles in a gas is associated with kinetic energy. This energy corresponds to the particles' motion and is dependent on their velocity and mass.
1. 10 J of heat are removed from a gas sample while it is being compressed by a piston that does 20 J of work. What is the change in thermal energy of the gas Does the temperature of the gas increase?
10 JoulesConservation of energy, assuming there are no other losses in the system, and 20 Joules are introduced by compression, and 10 Joules are removed by heat transfer, the remaining 10 Joules must be absorbed as increased thermal energy of the gas.
What energy transformation occurs in a gas oven?
chemical energy to thermal energy(heat energy)
When a gas is heated is all of the absorbed energy converted to kinetic energy or potential?
When a gas is heated, the absorbed energy mostly gets converted to kinetic energy of the gas particles, which results in an increase in their speed and therefore temperature. Some of the energy might also be converted to potential energy, such as increasing the distance between the gas particles.
What type of energy is associated with random motion of particles in sample of gas?
thermal energy or kenetic energy

What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
As the temperature of a gas sample increases, the kinetic energy of the gas particles also increases. This is because temperature is a measure of the average kinetic energy of the particles in the sample. Therefore, an increase in temperature corresponds to an increase in the average kinetic energy of the gas particles in the sample.
What happens to the density of a gas sample collected in a balloon as the sample is heated?
As the gas sample in the balloon is heated, the gas molecules gain more kinetic energy and move faster, causing them to spread out and occupy a larger volume. This results in a decrease in density since the same amount of gas now occupies a larger space.
When a sample of liquid boils thermal energy increases or decreases?
When a sample of liquid boils, thermal energy increases. This added thermal energy allows the molecules to overcome intermolecular forces and transition from the liquid phase to the gas phase. As a result, the temperature of the liquid remains constant during the boiling process, even though energy is being supplied.

What energy transformation takes place in an engine?
In steam and combustion engines, thermal energy is changed to mechanical energy. Either heated gas or heated fluid is created that exerts force to turn the engine. In combustion engines, chemical energy becomes thermal energy which becomes mechanical energy. In electrical engines (motors), electrical energy is changed to mechanical energy by the manipulation of magnetic fields.
If a sample of gas is heated what happens to the most probable speed of the gas?
When a sample of gas is heated, the average kinetic energy of the gas molecules increases, leading to an increase in their speeds. Consequently, the most probable speed, which is the speed at which the largest number of molecules are moving, also increases. This is due to the direct relationship between temperature and the average kinetic energy of the molecules in the gas. Therefore, as the temperature rises, the most probable speed of the gas molecules rises as well.
How does air behave as it is warmed or cooled?
when air(gas) is cooled(thermal energy is removed) its molecules slow down and it becomes a liquid(condensation) when air(gas) is heated(thermal energy is added) its molecules speed up, but it wont change into a different phase until gas is heated to a temperature above 10,000 C, which removes electrons from the atoms
How does a ball get pumped up by the sun if it is left outside?
If a soccer ball that is otherwise able to hold its pressure fairly well is heated by the sun, it will, indeed, increase its pressure. Thermal energy is transferred to the air (which is already compressed) inside the ball, and it causes the gas atoms and molecules to increase their thermal energy. This thermal energy causes increased vibration and increased "bouncing around" among the heated gas particles. The increased kinetic energy added to the air by the heat of the sun has increased the pressure in the ball.
When a gas is heated does all of the absorbed energy convert to kinetic energy If not please tell what it is converted to part kinetic and part potential energy or just potential energy?
The gas will have thermal energy given by its specific heat capacity (at constant pressure or volume depending on the situation) times the rise in temperature. This thermal energy is possessed because of the increased kinetic energy of its molecules, due to the rise in temperature.
