Energy needed to change material from solid to liquid?
heat is a mesure of energy the more energy the hotter it is so depending on its melting point is how much energy/heat is needed
How does melting point of bromine change with external pressure?
Bromine, as many other materials gets a higher melting point when pressure is low [less energy is needed to set molecules free] and lower melting point when pressure is high [more energy needed].
What is needed for matter to change phase?
Heat is needed for matter to change form eg: Melting, condensation, etc.
Why is energy required for the melting or boiling process?
Energy is required in the melting process because high is needed to melt something
What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
Melting gain or loss thermal energy?
For melting thermal energy is needed to work against the attractive force of crystallization. So heat gained from outer force is lost in doing such a work
What energy is needed to change a material from a liquid to a solid?
energy
When you melt ice what heat is it called?
When melting ice, you are moving from a solid to a liquid. Any state change from a solid to a liquid is called the heat of fusion. In other words, whenever melting takes place, the amount of energy needed is referred to as the heat of fusion.
If heat energy is needed to change phase from a solid to a liquid List the possible sources of the heat needed for this phase change in your baggie Which source do you think is the possibility and why?
The ice, the milk, the salt, the air in the baggie, the heat from your hands. The milk is the best source of heat energy for the melting process because it is a liquid and stores more energy for the phase change than the air or salt do. Your hands do not touch enough area to be effective sources of heat. ~*~
What is needed to do work or cause change?
Energy
What is needed to work or cause change?
Energy
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
