What else can I help you with?
Would the density in liquid become more dense or less dense when thermal energy is added?
When thermal energy is added to a liquid, the molecules will move faster and further apart, causing the liquid to expand and become less dense.
What happens when an object losses thermal energy?
When an object loses thermal energy, its temperature decreases. This loss of thermal energy can occur through conduction, convection, or radiation. As the object cools down, its molecules will slow down and move less vigorously, resulting in a decrease in temperature.
What happens to particles in a substance as thermal energy decreases?
As thermal energy decreases, the particles in a substance slow down and have less kinetic energy. This may cause them to move closer together, leading to a decrease in the substance's volume or a change in state, such as from a gas to a liquid or a solid.
What causes the transfer of thermal energy during convection?
The movement of matter during convection is what transfers thermal energy.The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases). Convection is usually the dominant form of heat transfer in liquids and gases.
Does gold conducts thermal energy?
More or less everything conducts thermal energy, but to different degrees.
Does solid liquid have less or more thermal energy?
It has less because you add a solid and liquid together and you get less.
Would the density in liquid become more dense or less dense when thermal energy is added?
When thermal energy is added to a liquid, the molecules will move faster and further apart, causing the liquid to expand and become less dense.
How does a gas become a liquid?
By cooling. With less thermal energy, the kinetic energy of each molecule becomes less. Therefore some of the gas molecules can no longer escape the attraction of like molecules. As they join together we perceive them as liquid.
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.
Does a gas lose or gain thermal energy in condensation?
The gas begins to cool down, and lose thermal energy, and moves up in the ladder of the 3 states of matter. Gasses condense into liquids, liquids turn into solids. The higher up you go, the less thermal energy the object has.
Will an object will be a net radiator of energy when its thermal energy is less than that of its surroundings?
No, an object will not be a net radiator of energy when its thermal energy is less than that of its surroundings. In this case, the object will instead absorb thermal energy from its surroundings in an attempt to reach thermal equilibrium.
What happens when an object losses thermal energy?
When an object loses thermal energy, its temperature decreases. This loss of thermal energy can occur through conduction, convection, or radiation. As the object cools down, its molecules will slow down and move less vigorously, resulting in a decrease in temperature.

As thermal energy decreases, the particles in a substance slow down and have less kinetic energy. This may cause them to move closer together, leading to a decrease in the substance's volume or a change in state, such as from a gas to a liquid or a solid.
Why 1g of iron contains less energy than 1g of water?
1 gram of iron contains less energy than 1 gram of water primarily due to the difference in their specific heat capacities. Water has a high specific heat capacity (about 4.18 J/g°C), meaning it can store more thermal energy per gram per degree of temperature change. In contrast, iron has a lower specific heat capacity (about 0.45 J/g°C), indicating it can store significantly less thermal energy under the same conditions. This difference results in water having a greater energy content for the same mass compared to iron.
What causes the transfer of thermal energy during convection?
The movement of matter during convection is what transfers thermal energy.The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases).

How does liquid become gas?
Liquid becomes gas through a process called evaporation. When liquid is heated, the molecules gain energy and move faster, overcoming the forces holding them together in the liquid state. Eventually, the molecules have enough energy to break free from the liquid and turn into a gas.
Which cable has less losses?
Thicker cable loses less thermal energy.
