Does kinetic energy increase or decrease when a liquid changes to a gas?
the kinetic energy increases
How do you change solid water to liquid and liquid water to gas?
You can change both of these by increasing or decreasing the speed of the molecules (kinetic energy), or by increasing or decreasing the heat applied (thermal energy). If you want to melt ice, you can increase the kinetic energy by increasing the thermal energy. The opposite occurs if you want to freeze water.
What happens to the thermal energy of a substance during a change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
What is the difference between temperature and thermal energy?
Temperature is the average kinetic energy of all particles, but thermal energy is the total amount of energywithin a solid, liquid or gas. Thermal energy implies that energy is being produced and maintained in a closed system. Temperature is a stable measurement of something.
Is Kinetic energy a solid liquid or gas?
Kinetic energy is the energy of motion. Heat is a form of kinetic energy (the movement of individual atoms or molecules) so the liquid phase contains more kinetic energy than the solid and the gas phase has more kinetic energy than the liquid phase. However, kinetic energy can also be imparted to a mass as a whole in which case if the total mass of the phases was constant the this imparted kinetic energy would be the same for all phases.
Is the kinetic energy of hydrogen gas greater or less than the kinetic energy of liquid hydrogen How do you know?
You can only refer to the Kinetic Energy of the Gas Molecules in this manner, not the entire Volume of the Gas as an Object. To become a Gas Hydrogen must increase its Thermal Energy to the point that it goes from Liquid State to Gaseous State. This increase in Thermal Energy causes and increase in the Motion of the Hydrogen Molecules...increasing their Kinetic Energy. If cooled to Absolute Zero Temperature their KE goes to Zero and Molecular motion Stops.

the kinetic energy increases
How does the addition of heat to a liquid affect its average kinetic energy?
It would increase its average kinetic energy which would be apparent by an increase in temperature.
What does an increase of temperature do to the KE of a liquid?
It increases the Kinetic Energy

A person places a metal spoon that is at room temperature into a bowl of hot soup how will the thermal energies of the spoon and the soup be affected?
the spoon will increase in thermal energy, and the soup will decrease in thermal energy. Reason: Thermal energy is the total of all the kinetic and potential energy of the atoms in an object. When the thermal energy of a substance increases, its particles move faster. If the thermal energy of a solid increases enough, it melts into a liquid. The liquid state of a substance always has a higher thermal energy than its solid state. If the liquid continues to gain thermal energy, its particles speed up more. When the particles of a liquid have absorbed enough energy to escape the forces between them, the liquid becomes a gas. The substance has undergone another phase change. As the total kinetic energy of the particles in an object increases, the object gets warmer. Heat flows from a warmer object to a cooler one.

When a liquid becomes a solid where does the heat energy in the liquid go?
A gas has more heat energy, often called thermal energy, than a liquid, even if both the liquid and gas are at the same temperature. Consider that the gas molecules have more thermal energy than liquid molecules of that same substance. The gas molecules are "free" to move around more because they have more kinetic energy than molecules of the liquid. And kinetic energy is function of thermal energy. If we consider the case of water molecules to illustrate our point, when a pan of water is boiling, the water molecules escaping the pan as a gas have more kinetic energy than the ones making up the liquid water that is still in the pan. Also consider the case of water that is evaporating. Wet your finger and blow on it. The liquid water on your finger cools as the evaporating water molecules take thermal energy from that liquid to make their change of state possible. It takes an increase of thermal (heat) energy to change a liquid into a gas.
How do atoms in a liquid transfer heat to nearby atoms?
On a molecular scale, thermal energy is the kinetic energy of individual particles. In a liquid, this thermal energy is transferred to nearby atoms by collisions; a high-speed particle in the liquid collides with a lower-speed particle, transferring some kinetic energy from the high-speed particle to the low-speed particle. When this happens with a large number of particles, thermal energy transfer results.
How does in thermal energy cause matter to change from one state to another?
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.
How does change in thermal energy causes matter to change from one state to another?
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.
Does thermal energy can cause matter to experience a change of phase why?
Yes because when the thermal energy of a substance increases, it's particles move faster. If the thermal energy of a solid increases, it's particles melts into a liquid. The liquid state of a substance always has a higher thermal energy than it's solid state
