High pressure under skaters shoes lowers melting point of ice explain?
Under the pressure exerted by skates, the melting point of ice decreases due to the compression of the ice crystals. When pressure is applied, the ice molecules become more tightly packed together, causing a decrease in the amount of energy required for the molecules to transition from a solid to a liquid phase. This is why the pressure from skate blades can lead to the melting of ice beneath them, allowing for smooth gliding.
What happens if I increase the pressure to solid water?
If you put pressure on ice it will melt.
What would have more vapour pressure pure ice or sweet ice?
Both will have same vapour pressure as salt{NACL} would get trapped in ice and in solid iced state get seprated from pure ice crystals. so in case melting of ice in soln state pure water will have more vapour pressure but in solid state both will have same vapour pressure.
What happens to ice when applied to platinum?
No, but ice cubes and a little scotch can soften a heart of stone.
Are ice crystals example of freezing?
It depends. If the ice crystals are forming, then yes, the water is freezing. If you just mean ice crystals, just there not doing anything, then no.
When do crystals form?
Snow crystals form when water vapor condenses directly into ice. This happens in the clouds.
If we put pressure on ice then how can it melt?
When pressure is applied to ice, the melting point decreases. This means that even if the ice is below its normal melting point, the pressure can cause it to melt. This is known as pressure melting or regelation.

How much pressure is applied to convert carbon dioxide into dry ice?
6.5 bars

What type of precipitation forms from ice crystals?
Ice crystals don't precipitate. Precipitation of crystals happens when you create a supersaturated solution, and you do THAT by heating a solvent, adding enough solute to make a saturated solution at that temperature, filtering out the undissolved solute, and letting the solution cool. Ice crystals form.

No, but ice cubes and a little scotch can soften a heart of stone.
Are ice particles and ice crystals the same thing?
no Ice particles fall from the sky but Ice crystals form on the ground.

It depends. If the ice crystals are forming, then yes, the water is freezing. If you just mean ice crystals, just there not doing anything, then no.
What are the three ways in which ice crystals can form in a cloud?
Vapor deposition (Diffusional growth) - The vapor pressure over an ice crystal is much lower than that over a liquid droplet. Because atmospheric properties tend to move from regions of higher pressure to regions of lower pressure, water vapor surrounding liquid droplets tends to diffuse towards the ice crystals and deposit on them. This creates a deficit of water vapor above the droplet, which evaporates to make up for it. The newly evaporated water vapor also diffuses to the ice crystal, so that the ice crystal grows at the expense of the water droplet Accretion - As ice particles fall through the cloud at a higher velocity than cloud droplets, it collides and collects the supercooled droplets, which freeze upon contact with the crystal. The collected droplets are known as rime. Aggregation - Ice crystals falling through the cloud can collide with each other and stick together. This process is particularly efficient at temperatures near 0C, because the thin liquid water coating that forms on the partially melted crystals can act as an adhesive between the crystals.
