Water reduces the melting point of rock.
It doesn't. It does slow the melting of rock, but only because of the specific heat of water. (i.e. you've got to heat the water too.)

Yes
The presence of water lowers the solidus temperature of rocks at a given pressure. It drastically changes the melting temperature by a vast amount.
The two main factors that affect the temperature at which rocks melt are the composition of the rock and the pressure acting on it. Different minerals have different melting points, so the composition of the rock will determine its melting temperature. Additionally, pressure can increase or decrease the melting temperature of rocks, with higher pressure generally increasing melting temperature and lower pressure decreasing it.
the hotter the water the faster the ice will melt
Adding salt to melting ice lowers the freezing point of water, causing the ice to melt at a lower temperature. This results in faster melting of the ice.
The presence of water can lower the melting temperature of a rock by facilitating the movement of ions and promoting the process of melting. Water reduces the viscosity of molten rock, making it easier for the rock to melt at lower temperatures.
A change in temperature affects the melting of ice by either speeding up or slowing down the process. When the temperature increases, the ice absorbs heat energy and melts faster. Conversely, when the temperature decreases, the ice absorbs less heat energy and melts slower.
Higher GC content in DNA is associated with a higher melting temperature, as GC base pairs have three hydrogen bonds compared to two in AT base pairs, making them more stable. Therefore, DNA sequences with higher GC content require higher temperatures to denature during melting compared to sequences with lower GC content.
In theory yes: increasing pressure will increase the melting point mostly (not for ice!). In practice: it is hardly noticable, not significant at all, for most solid materials.Pressure increases the melting point of rock. The molecules are packed tighter together and thus take more energy to liquefy.
Garlic does not affect the melting point of ice. The melting point of ice is primarily determined by the temperature of its surroundings and the amount of energy present to break the hydrogen bonds holding the ice together. Garlic does not play a role in this process.
