What else can I help you with?
Sublimation is th change from a soild to a gas with out becoming a liquid first true or false?
True.
True or False Sublimation is a change from solid to gas?
Yes, sublimation is a change from solid to gas.
Is it true melting is considered an sublimation change because energy is gained by substance as it changes stae?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Sublimation is a phase change in which a solid moves directly into the gas phase. Both melting and sublimation are two types of physical change.
True or false The melting temperature of a solid changes with the amount of material?
True
True or false an impurity raises the melting point of an organic compound?
False. In general, impurities lower the melting point of an organic compound by disrupting the crystal lattice structure.
Do All minerals have the same melting point True of False?
False, all minerals DO NOT have the same melting point
Is this true or false displacement includes both distance and direction?
false
The upper respiratory tract includes the lungs. false or true?
false
The term fraud includes unauthorized actions by both Cardholders and Merchants true or false?
false
Is it true mercury the planet use to be as big as earth and now it is not because the sun is melting it?
false
when There is no requirement to take action to identify and discipline those responsible for the unauthorized disclosure of Controlled Unclassified Information?
False
Is it true or false that the crystal lattice of ionic compounds affects their melting and boiling points?
True. The crystal lattice structure of ionic compounds plays a significant role in determining their melting and boiling points. The stronger the forces holding the ions in the lattice together, the higher the melting and boiling points of the compound.
