When a sample of liquid is cooled then what happens to the thermal energy?
When a sample of liquid is cooled, its thermal energy decreases as the molecules lose kinetic energy and move more slowly. This reduction in thermal energy can lead to a decrease in temperature and may eventually cause the liquid to solidify if cooled sufficiently. The lost thermal energy is typically transferred to the surrounding environment.
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.
Thermal energy is added to four identical samples of water. what increases in each sample?
When thermal energy is added to four identical samples of water, the temperature of each sample increases, leading to an increase in the kinetic energy of the water molecules. This rise in temperature can also result in an increase in the potential energy of the water molecules as they begin to move further apart, especially as the water approaches its boiling point. Additionally, if sufficient thermal energy is added, the water may eventually change state from liquid to gas (steam), increasing the internal energy further.
What happens to the molecules that make up a sample of liquid water when the sample absorbs molecules that make up a sample of liquid water when the sample absorbs enough heat to reach the boiling poi?
When a sample of liquid water absorbs enough heat to reach its boiling point, the increased thermal energy causes the water molecules to move faster and break the hydrogen bonds holding them together. As the temperature reaches 100°C (at standard atmospheric pressure), the molecules gain enough energy to overcome these intermolecular forces, transitioning from the liquid phase to the gas phase, resulting in the formation of water vapor. This process is known as vaporization or boiling.
Why don't particles stop moving?
particles move because when they do not the attraction of a particle and another stops making the particle theory wrong particles are always moving it what makes the attraction stronger

What type of energy is associated with random motion of particles in sample of gas?
thermal energy or kenetic energy

What happens to the thermal energy of a substance as its temperature increases?
As the temperature of a substance increases, its thermal energy also increases. This leads to greater kinetic energy of the particles within the substance, causing them to move faster and creating more thermal energy.
What happens to a sample of matter when its particles lose kinetic energy?
A loss of kinetic energy in the atoms or molecules of a sample of matter will result in the cooling of the sample. That sample will get colder as remove thermal energy from it. The atoms/molecules of a substance have kinetic energy associated with them. This kinetic energy is the result of atomic and/or molecular motion. As a sample of matter cools, the atoms and/or molecules will lose mobility. Loss of mobility and vibrational energy, which are forms of kinetic energy, will become apparent when thermal energy is removed from the sample.
Condensation is an important phase change that commonly occurs in the atmosphere. suppose a 1-m3 sample of air at sea-level pressure containing 4 g of water vapor was cooled such that all 4 g condense?
The 4 g of water vapor in the 1 m3 sample of air will condense into liquid water when cooled. This phase change releases latent heat energy to the surroundings. The final state will be a mixture of dry air and liquid water in equilibrium.
Which type of energy would exist in a liquid sample but not in a gas sample of the same molecular compound?
You think probable to intermolecular forces.
What is the principle of differential thermal analysis?
Differential thermal analysis (DTA) is a thermal analysis technique that measures the temperature difference between a sample and a reference material as they are heated or cooled. The principle relies on detecting changes in thermal properties, such as phase transitions, crystallization, or chemical reactions, which manifest as temperature differences. These differences are recorded and plotted against temperature, providing insights into the thermal behavior and stability of the sample. DTA is commonly used in materials science, chemistry, and pharmaceuticals to study thermal characteristics and material properties.
Why can the temperature of a substance remain the same even if the substance is absorbing thermal energy?
That can't happen, unless the object is losing thermal energy out the back doorat the same rate as it's absorbing thermal energy in front where you're watching.There's no getting around the rules:More thermal energy inside = higher temperature.Less thermal energy inside = lower temperature.Excuse me, I just thought of the exception ... that's when the substance is changingstate, between solid / liquid / gas.The reason is that, for example, it takes more thermal energy for the moleculesof water to act like a liquid than it takes for them to act like a solid, even thoughthe water and the ice are both at the same temperature.Holy moley ! There's another one. If you pump thermal energy into a sample ofgas AND let the gas expand at the same time, you can adjust things so thatthe temperature remains constant.
What term refers to the total kinetic energy of the particles in a material?
Thermal energy is the term for total kinetic energy in a substance, according to a 5th grade science book. There may be other forms of energy in a substance, but thermal energy is the total kinetic energy.Temperature is a measure of the average kinetic energy of the particles in a sample.
If you were able to measure the motion of all particles of a sample and you used you would actually e measuringedthis data to find the average?
Using this data, you could calculate the average kinetic energy of the particles in the sample. Kinetic energy is directly related to motion and is determined by the mass and velocity of the particles. By finding the average kinetic energy, you can understand the overall thermal energy of the sample.
