What atomic change produces the largest amount of energy?
The atomic change that produces the largest amount of energy is a nuclear atomic change. This is when an atom is hit with another elementary particles and releases a large amount of energy.
Is liquid to solid exothermic?
No. Going from solid to liquid at constant temperature is an endothermic process. The required amount of energy is called "heat of fusion" of the material that changes state.
What is the amount of material that an object has in it is the ojects mass energy or volume?
mass.
The of a material is the amount of energy it takes to raise the temperature of you kg of the material 1 K?
specific heat capacity
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
The amount of heat energy required to raise the temperature of a unit mass of a material one degree is?
Heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a material one degree.
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
Amount of energy it takes to change a material from a solid to a liquid is the heat of?
Heat of fusion.
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
What is specific latent of fusion?
It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
How much energy is taken to change water into a solid?
The same amount of energy that is required to change it from a solid to a liquid. About 334.0 kJ/kg.
What means that a large amount of energy is required to change the waters temperature?
Specific heat
What energy is the minimum amount of energy required for substances undergo change to produce one or more different substances?
activation energy
What is specific latent heat of vaporisation?
Is the amount of energy required to change 1kg of liquid into gas with no temperature change.
A materials heat of funsion gives the ammount of energy needed to?
The heat of fusion, also known as the enthalpy of fusion is how much energy is required to melt a solid to a liquid. This is the energy required to change the phase of the material - not the temperature. In fact at the melting point the heat capacity becomes infinite because all the energy is being used to change state and not temperature.As energy cannot be created or destroyed it is reasonable to assume it is the same amount of energy for a liquid to turn into a solid, which it is.So if energy is needed to change the phase of ice into water, the same amount of energy is released when water changes back into ice.
What is the energy required to go from liquid to gas called?
The latent heat of vaporization
The heat of fusion is defined as the energy required at constant temperature to change 1 unit mass of a?
The heat of fusion is the amount of energy required to change 1 unit mass of a solid to a liquid at constant temperature.
