When an obeject is changing from a liquid to a solid does the energy increase or decrease?
The energy level decreases.
How can liquid be turned into a solid?
the solid must reach its melting point which varies with every substance
does solid to gas increase or decrease tempearture?
Increase
How does in thermal energy cause matter to change from one state to another?
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.
What happens to the thermal energy of a substance during a change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing

If you were changing a gas to a liquid to a solid what thermal change would be involved?
The thermal change that would be involved is a negative one. A gas must decrease in temperature to become a liquid and eventually a solid.
What phase has the lowest entropy?
Solid to liquid
Did the snows entropy increase or decrease while in your hand?
Increase. The heat from your hand will melt the snow causing it to go from a low entropy solid state to a higher entropy liquid state.
What process causes changes of state?
In a word, temperature. A physical change will change the matter's state based on it's temperature. For example, water, H2O. You can increase the temperature to 212oF and it will change state from a liquid to a gas. You can decrease the temperature to 32oF and it will change state from a liquid to a solid. To answer your question, the process of doing so would be increasing or decreasing temperature of matter.
What temperature does a gas change?
any increase in temperature will cause gas to occupy a larger volume, any decrease will shrink the volume to a point it becomes liquid. further decrease will cause a solid to form. at -273 degrees celsius everything is solid
When a substance changes from a solid to a liquid its density normally decreases. What is happening to the substance's mass and volume to cause this decrease in density?
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
