In an experiment comparing melting points of different substances, if a researcher used twice the amount of one substance but kept all other conditions the same, how would this affect the melting point measurement?
1 )
The melting point would be higher because more substance requires more energy to melt
2 )
The melting point would be lower because larger quantities melt more easily
The melting point would remain the same because it is a property of the substance
4 )
The melting point would be impossible to determine because of the excess substance
