What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
Which trend decreases for metals down a group?
Melting Point
How does salt affect the melting and freezing point of water?
Salt decreases the freezing point of water and increases the boiling point of water.
How does the melting point of water change as pressure increases from1atm?
The melting point of water decreases as pressure increases from 1 atm. At pressures above 1 atm, water requires a lower temperature to melt because the increased pressure helps to stabilize the solid phase.
What happens to the temperature of a solid at its melting point when heated?
The intermolecular forces of attraction in the solid decreases as it is heated and the solid melts (solid converts to liquid) at its melting point.
When a substance is melting the temperature of the substance what?
it decreases.

Melting Point
How does atmospheric pressure affect the melting point of a liquid?
I assume you mean melting point of a solid (if it's liquid it has already melted). It decreases as you increase the pressure.
When a solid is heated to its melting point what happens?
The intermolecular forces of attraction in the solid decreases as it is heated and the solid melts (solid converts to liquid) at its melting point.
Does the salt decreases the melting point of ice?
Adding of any type of impurity in water decreases its melting point. You might have studied that depression in freezing point is a "colligative" property according to which adding of any impurity to a pure liquid decreases the melting point and increases the boiling point of that liquid. So, adding of salt is not the only method of decreasing the melting point.
When common salt is mixed with ice its melting point is?
The melting point of ice decreases when common salt is mixed with it. This is due to the colligative property of salt, which interferes with the hydrogen bonding between water molecules, making it harder for the ice to stay in a solid state.
How does salt affect the melting and freezing point of water?
Salt decreases the freezing point of water and increases the boiling point of water.
To increase Melting and boiling point of Zinc what is to be done?
To increase MP and BP point of Zinc u should add some impurities in it. The addition of impurities always decreases the melting point .
Will the melting point of ice increase or decrease when salt is added on it?
The melting point of ice decreases when salt is added.
