Which change in state requires that energy be added to the substance?
Melting solid into liquid requires energy to be added to the substance.
Changing from one state to another requires a change in temperature or a change in .?
energy.
Why does change in state requires a change in energy?
States need regulations on energy to save the country money. The US is in debt about $13 trillion so they need to save energy to save money. With the regulations, states will be supported with grants, and this will help the value of the dollar go up. It also saves the environment.
Why is energy not considered a state of matter?
Energy is not considered a state of matter because it is a property or characteristic of matter rather than a form of matter itself. Matter is composed of particles (atoms, molecules) that have mass and occupy space, while energy is a measure of the ability to do work or cause change in matter. So, energy and matter are distinct concepts in physics.
What kinds of energy are needed in this investigation to change the state of matter of the candle?
The energy needed to change the state of matter of a candle is primarily in the form of heat energy. When the candle is lit, the heat energy from the flame melts the candle wax, causing it to change from a solid to a liquid state. Further heating vaporizes the liquid wax, transforming it into gaseous wax molecules that combine with oxygen to produce light and heat energy.
Which change in state requires that energy be added to the substance?
Melting solid into liquid requires energy to be added to the substance.
Can 4 and 5 state of matter be the energy resource for future generation?
It isn't quite clear what you mean with "4 and 5 state of matter". The Wikipedia lists approximately 17 states of matter; any numbering in this list is more or less arbitrary. On the other hand, if you change from one state of matter to another, it might cost you energy, for example; such energy can be recovered (in theory) when the change is carried out in the reverse order. Thus, for example, it requires energy to convert liquid water to vapor; this energy is released again when the vapor condenses. The same happens with any other change of state. Thus, you can use a change of state to STORE energy temporarily, but not as a permanent ENERGY SOURCE.
Changing from one state to another requires a change in temperature or a change in .?
energy.
What can the state of matter be changed by?
A change in the state of matter occurs when heat energy is added or removed.
What is needed for matter to change it's state?
Energy

How do you change one state of matter to another?
To change one state of matter to another, you need to either add or remove heat energy. For example, to change a solid to a liquid, you would need to add heat energy to melt the solid. Similarly, to change a liquid to a gas, you would need to add heat energy to evaporate the liquid.
When matter undergoes change of state what does it absorb or release?
Energy.
What happens to heat during a change of state?
During a change of state, such as melting or boiling, heat energy is absorbed or released without a change in temperature. This heat energy is used to break the intermolecular forces holding the particles together, allowing them to move into a new arrangement. Once the change of state is complete, the temperature resumes changing.
What can changes energy?
Energy can change state of matter. Heat can be used to melt ice.
What happens to the temperature when matter changes state?
Quite often, the temperature doesn't change. For example: if you melt ice, you convert ice at 0 °C to water at 0°C. You need to put heat energy into the ice to melt it, but its temperature doesn't change. (The change of state itself requires energy - this is a type of potential energy.)
How does energy help to change the state of matter?
Heat (thermal energy) is the major reason for state change in matter. (Although ambient pressure modifies that at the liquid/vapor boundary.) Basically as energy increases matter moves from solid to liquid to gas to plasma.
