What state of matter has the most energy stored as interaction energy?
Solid
Which metal is ln liquid state under ordinary condition?
mercury
What is the Physical state of water at 15 degree Celsius?
Liquid state
Is water vapour in the liquid state?
yes, water vapour is in a liquid state
What are the differences between freezing melting and evaporation?
Changing the liquid state to solid state is known as freezing, changing from solid state to liquid state is known as melting and changing from liquid or solid state to gaseous state is known as evaporation.
What state of matter has the most energy stored as interaction energy?
Solid
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
Which metal is ln liquid state under ordinary condition?
mercury
Which type of energy is stored as a result of a change in position or condition?
Potential Energy (change of position) and latent energy (change of state condition as freezing)
What do you call the amount of energy needed to change a material from the solid state to the liquid state?
either potential or kinetic
What is the energy needed for a substance to change from liquid state to a gaseous state?
thermol
What is needed for the molecules in a solid state to change into the liquid state?
In order for molecules in a solid state to change to a liquid state, the substance needs to be heated. An increase in temperature causes more molecular movement (this leaves more space between each molecule) which results in what we see as the physical change from solid to liquid and then eventually liquid to gas.
Why is liquid nitrogen useful in storing food?
It is used in the freeze drying process, which allows certain foods to be stored in a dry state for a long time.
Why are iron and nickel in the liquid state in the outer core?
The molten condition may be due to the heat produced by radioactive elements
Evaporation is the process where a liquid changes from its what state to what state?
Evaporation is the process where a liquid state changes from its LIQUID state to a GAS state.
What Heat of is the energy needed for a substance to change from liquid state to a gaseous state?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
What is the state of the Union?
The State of the Union Address is given every year by the president to the congress. It gives his understanding of the condition of the nation and what is needed to govern it effectively.
