Why the inter-particle space increases on heating a solid at its melting point?
when we heat a substance its kinetic energy increases and due to this kinetic energy the force of attraction decreases and can no longer hold the particles together.
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
What happens to thermal energy when temperatures increase?
When the temperature of a material increase, thermal energy is added to the material. It also increases the kinetic and potential energy of the particles. When the temperature reach the boiling or melting point, the kinetic energy stays the same, but the thermal energy and the potential energy still keeps adding and increasing. And when ONLY the potential energy increase, the state of the material changes from one to another.
What happens when the temperature of a solid reaches is melting point?
The kinetic energy exceeds the inermolecular forces (Apex)
Why temperature remains same at melting point?
During the process of melting, heat energy supplied is used to weaken the bonds between molecules. This only increases their potential energy while the kinetic energy remains same. Since there's no change in kinetic energy, temperature remains constant.

What are the changes in the kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
The temperature at which the particles of a substance have more kinetic energy to transform is?
The melting or the boiling point.
What happens when kinetic energy is absorbed as an object moves toward the earth?
The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.

What happens to an apples kinetic and patential energy falling from a tree?
As the apple falls, its potential energy decreases while its kinetic energy increases, until it lands, at which point it has maximum potential energy.

Why does water molecule have a high boiling point and melting point?
hydrogen bonding increases the intermolecular attractions and therefore increases the boiling point and melting point.
How does velocity have an effect on kinetic energy?
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
What is melting or boiling point?
The melting point is the temperature at which a solid changes phases into a liquid. This is a result of the highly structured atoms of the solid, which have very little kinetic energy beginning to gain energy and dissociate. The boiling point is the temperature at which a liquid changes into a gas. This happens when the atoms/molecules of a liquid gain enough kinetic energy to escape the liquid and move into the gaseous state.
