What else can I help you with?
When you add thermal energy to a system what will happens to the kinetic energy of the molecules within the system?
When thermal energy is added to a system, the kinetic energy of the molecules within the system increases. This increase in kinetic energy causes the molecules to move faster and results in a rise in temperature.
What happens to a gas when you add thermal energy?
In this case the volume increase, the density is lower.
What happens to gas when you add thermal energy?
In this case the volume increase, the density is lower.
How can you add thermal energy to a substance without increasing its temprrature?
That happens when there is a phase transition; for example, when ice melts, it takes energy to convert ice at zero degrees, to water at zero degrees.
What happens if we add thermal energy to a liquid?
It will get hotter. Eventually it may evaporate.
What happens to matter to when you add thermal energy?
When thermal energy is added to matter, the particles within the matter gain kinetic energy and move faster. This increased movement causes the particles to spread out, leading to a change in phase (e.g., solid to liquid or liquid to gas) or an increase in temperature. Ultimately, thermal energy causes matter to change its physical state or temperature.
Can you add thermal energy to an object without increasing its temperature?
Yes, it is possible to add thermal energy to an object without increasing its temperature by changing its phase. For example, when ice is melting, thermal energy is being absorbed to break the bonds between water molecules without a change in temperature.
What happens when you add a thermal energy to a solid?
When thermal energy is added to a solid, the kinetic energy of the particles in the solid increases, causing them to vibrate more rapidly. This increased vibration results in a rise in temperature, causing the solid to expand in size. If enough thermal energy is added, the solid may reach its melting point and transition into a liquid state.
Does 1 kilogram of water have the same amount of thermal energy as 2 kilogram of water?
No they wouldn't, this refers to specific heat capacities. Generally, gold has a lower heat capacities than of water, thus it takes less energy to change the temperature of gold than it does to change the temperature of water. So if you add the same amount of heat to both systems of water and gold, the gold will be hotter than the water.
Does condensation add or remove thermal energy?
Condensation releases thermal energy. As vapor cools and condenses into liquid form, it releases heat energy into its surroundings.
What happens to the thermal energy if you drop an ice cube in a warm drink and it melts?
As water and ice have different temperatures, if we add them together then there will be an exchange of heat, due to which ice starts melting and water becomes cold. The heat required to melt the molecules of ice is provided by the molecules of water and this heat is the latent heat of fusion.
How can you add thermal energy to a substance without increasing the temperature?
You can add thermal energy to a substance without increasing its temperature by adding hot water. As the thermal energy of the substance increases, the particles of the substance expands. That is how you can open a bottle by putting it under hot water.
