Does thermal energy depend on amount of substance?
Yes, thermal energy does depend on the amount of substance. The more mass a substance has, the more thermal energy it can store. This is because thermal energy is related to the internal energy of a substance, which increases with the amount of substance present.
What causes thermal energy?
Thermal energy is caused by the movement of particles within a substance. This movement generates heat energy by increasing the internal energy of the substance. The temperature of a substance is a measure of the average thermal energy of its particles.
What happens to the molecules in a substance when thermal energy is removed?
When thermal energy is removed from a substance, the molecules lose kinetic energy and slow down. This often causes the substance to cool down as the molecules have less energy to move and vibrate. In extreme cases, the substance may undergo a phase change, such as from a liquid to a solid.
When a substance is blank it gains thermal energy?
When a substance is heated, it gains thermal energy. This increased energy causes the substance's particles to move faster and its temperature to rise.
What is conserved during a reaction?
Both mass and charge
Does the amount of substance change its thermal energy?
Yes, the more substance you have, the slower the temperature change.
What is the equation for meausuring the change in thermal energy?
The equation for measuring the change in thermal energy is: Q = mcΔT, where Q is the change in thermal energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
What change when the amount of a substance change?
total thermal energy
How is the thermal energy of a substance related to its state?
The thermal energy of a substance determines its state, since thermal energy, aka internal energy, is the energy the molecules in the substance have. If the energy exceeds the force holding the substance together the substance undergoes a phase change.The physical state of a substance is related to its temperature, the measure of thermal energy. The substance can change states depending on the temperature, e.g. boiling.

How can the temperature of substance remain the same even if the substance is absorbing thermal energy.?
For example, when ice is melting, the absorbed thermal energy is used to change the phase of the substance - a type of potential energy.
Does thermal energy need to be conserved?
Yes, thermal energy can be conserved in a system through processes like insulation or heat exchange. However, thermal energy can also be transformed into other forms of energy or lost to the surroundings, so conservation of thermal energy is not always guaranteed.
How can the temperature of a substance remain the same even if the substance is absorbing thermal enerrgy?
The temperature of a substance can remain the same during absorbing thermal energy if the substance is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed thermal energy goes into breaking intermolecular bonds rather than increasing the temperature. Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
Formula to find thermal energy?
The formula to find thermal energy is: Q = mc∆T, where Q is the thermal energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ∆T is the change in temperature.
