When a solid melts do its particles gain or lose heat energy?
A material must gain energy both before and during melting.
Why would particles speed increase if heat was added?
Any object consists of particles. In a solid they are close together and do not move much. In a liquid the particles can move more freely past each other as they have more heat energy. In a gas the heat energy is largest and the particles move fastest. By heating any object we add heat energy to it. This speeds up the particle movement as the energy increases. It also expands the bonds between the particles and, if this goes far enough, the object changes state. (Ice melts when heated from solid to liquid)
What is happening to the particles and their energy when an object changes from a solid to liquid?
Energy is entering the system bc to change from solid to liquid there must be heat. Also the particles are now less dense and moving around more.
Why does ice cream melts quickly on a hot day?
Because heat is a form of energy, it causes particles to move faster. When particles move faster, they bump against each other and create more heat. Energy is what causes a solid to melt into a liquid (And sometimes sublime into a gas) and causes that liquid to turn into a gas.
Is heat added or released during freezing?
This is latent heat. When a liquid freezes heat is released, and when it melts the same amount of energy must be supplied. Similarly when a liquid changes to a vapor, or when a vapor condenses, heat must be supplied or is released. Latent heat varies from one substance to another, and can be quantified as so many calories per gram or kilogram, you can find data in reference tables

When heat is being supplied to a solid then what does the heat energy do to the particles of solid?
Adding heat energy will usually increase the temperature. At the level of the individual particles, the particles will vibrate faster.
When heat is supplied to a solid substance what happens to the energy?
The energy must be supplied to the solid so that it melts.
When ice melts what happens to the particles of solid water?
when u melt ice the hot particles transfer heat to the cold particles (ice) and the hot particles lose kinetic energy and the cold particles gain kinetic energy till the bonds relax and reaches the same temp
What happens to heat energy when a substance changes from solid to liquid?
it melts

How does heat conducting work?
When energy is transfered to something which conducts heat, the particles in the solid object start to vibrate. As more energy is transfered to the particles, it spreads across the solid objects particles. The hotter the solid, the more it's particles vibrate.

How does adding energy to matter by heating it affect the energy of its particles?
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.
What causes the phases change when solid iron melts into liquid iron?
Heat energy does.
What happens when heat is added to a solid?
It melts into a solid.
How do you change something from a solid to a liquid?
by adding energy, that is, heat. the solid then melts into a liquid while keeping all its phyical properties.
