Answer is C.
An increase in motion and less attraction between particles
An increase in motion and less attraction between particles
Adding heat energy will usually increase the temperature. At the level of the individual particles, the particles will vibrate faster.
You shouldn't think of "energy" as something that can be touched, like a solid, liquid, or even gas. Energy is more like the result of certain calculations; it isn't really a "substance", though people sometimes do tend to talk about energy as if it were - for example, energy "flowing" from one place to another.
Adding heat will do one of the following, or both: * The temperature of the substance increases. The individual particles move faster; their kinetic energy increases. * The substance changes its state (for example, when ice melts, it changes from solid to liquid). The potential energy of the particles increases.
Solid has more energy. It has extensive energy as compared to liquid and gas.

You are adding heat/energy. It is melting.
At its melting point (assuming it has one).
You are adding heat/energy. It is melting.
hotter and brings it closer to its boiling point
by adding energy, that is, heat. the solid then melts into a liquid while keeping all its phyical properties.
Adding heat energy will usually increase the temperature. At the level of the individual particles, the particles will vibrate faster.
Changing phase (solid, liquid, gas) requires energy. Adding energy allows the molecules to move apart and solid change to liquid or liquids change to gases.
to either melt of explode
From solid to liquid,liquid to a gas, solid to a gas is called sublimation. Generally it requires adding or giving out energy depending which direction it is going.
Melting is when you heat something up and it turns from a solid state into a liquid state, such as adding heat to ice (solid) melts it to water (liquid). Freezing is the opposite, so cooling a liquid until it becomes a solid.
