Why does a soild change to liquid when heat is added?

Explanation:

solid is particles packed up together like a family.

liquid is made out of particles as well but the are a little spaced out like a bunch of friends going home after a busy school day.

A solid changes state because when heat is applied it states changing state into a liquid.

like you freeze an ice cube and when it out on a summer day in a drink it starts melting AKA (A SOLID + HEAT =A LIQUID

Explanation:

Solid changes to liquid when heat is applied and the heat reaches melting point of the particular solid. It is at that point that the solid's strong intermolecular forces is weakened .

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
