What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
When a substance is heated it must gain electrons and energy?
Yes, it gains kinetic energy, for instance, when water is heated into water vapours the molecules of water vapour move faster than the molecules of water. This is because the water vapour has more kinetic energy than water.
What is happening to the molecules of a substance when they are heated or cooled?
When a substance is heated, the molecules gain kinetic energy and move faster, causing them to vibrate and collide more frequently, which increases the temperature of the substance. When a substance is cooled, the molecules lose kinetic energy and move slower, reducing the frequency of collisions and vibrations, which lowers the temperature of the substance.
How much energy is released when a substance is cooled to its original temperature?
When a substance is cooled to its original temperature, no energy is released. Cooling a substance typically involves removing energy from the substance, but this process does not generate energy. The energy removed is used to lower the temperature of the substance.
As sample of matter is heated it's particles do what?
As the individual atoms are warmed up, they move faster causing the substance to expand slightly. As a substance has energy added to it through heating, its Kinetic Energy becomes greater. Kinetic energy is the energy of Motion - the more the kinetic energy of the atoms of a substance means the faster the speed of motion of these same atoms.
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 happen to the average energy of the molecules in a substance when it is heated?
They increase in energy.
In the equation Q mcΔT c represents .?
The specific heat of the substance being heated.
What is the equation for calculating the energy transferred when a substance is heated and its temperature rises?
The equation for calculating the energy transferred when a substance is heated and its temperature rises is Q = mcΔT, where Q is the energy transferred, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
When a substance is heated what happens to kinetic energy of particles?
When a substance is heated, the kinetic energy of its particles increases. This leads to the particles moving faster and colliding more frequently with each other and the container they are in.
When a substance is heated it must gain electrons and energy?
Yes, it gains kinetic energy, for instance, when water is heated into water vapours the molecules of water vapour move faster than the molecules of water. This is because the water vapour has more kinetic energy than water.

When a substance is cooled, the molecules lose kinetic energy and move slower, reducing the frequency of collisions and vibrations, which lowers the temperature of the substance.
What is the transfer of energy as heat by movement of the heated substance itself?
Convection is the transfer of energy as heat by movement of the heated substance itself. This process involves the movement of molecules in a fluid (liquid or gas) due to differences in temperature, causing the warmer substance to rise and the cooler substance to sink.
When a substance is heated and the average kinetic energy remains low where has the energy gone?
If a substance is heated, it will either get hotter, or it will change its phase - for example, when ice at 0 degrees Celsius is melted to water at 0 degrees Celsius. In this case, the heat energy is converted to a type of potential energy.
How much energy is released when a substance is cooled to its original temperature?
When a substance is cooled to its original temperature, no energy is released. Cooling a substance typically involves removing energy from the substance, but this process does not generate energy. The energy removed is used to lower the temperature of the substance.
What are the changes in the kinetic energy as a substance is heated to its melting point?
As a substance is heated to its melting point, the kinetic energy of its particles increases, causing them to move more rapidly. This increase in kinetic energy leads to a rise in temperature until the substance reaches its melting point. At the melting point, the kinetic energy is used to overcome the forces holding the particles together, leading to the substance changing from a solid to a liquid state.
