Water can't melt!!!
Of the three options, plastic has the lowest melting point. Different types of plastics have varying melting points, but in general, they melt at lower temperatures compared to both water and timber.
Ethylene glycol is antifreeze. The mixture has a lower melting point than pure water.
The melting point of salt water is even lower than pure water.
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
It has a lower melting point than water.
Because the melting point of the plastic used to make the bottle is lower than the temperature of the water that you have put in it. Plastic bottles are 'blow molded'. Basically air is forced inside a small piece of hot plastic and it expands like a balloon, except that this 'balloon' is inside a form or mold in the shape of the bottle. It is cooled and the bottle shape stays. If the softening point of the bottle is lower than the hot liquid poured in, then the plastic 'balloon' wants to shrink again.
To lower the melting point of wax, you can consider adding a small amount of mineral oil or vegetable oil to the wax before melting it. This will decrease the overall melting temperature of the wax. Alternatively, you can mix the wax with a lower melting point wax to create a blend with a reduced melting point.
Oil baths are typically used for high-temperature melting point determinations, where the sample needs to be heated to a temperature above the boiling point of water. Water baths, on the other hand, are used for lower temperature melting point determinations, as water has a lower boiling point compared to oil.
The freezing point of salted water is lower compared with the freezing point of pure water. So when melting frozen salt water is colder.
As the water content of rocks increases, the melting point typically decreases. This is because the presence of water lowers the melting point of minerals in the rocks by acting as a flux that promotes melting. The addition of water creates a eutectic point where the rock will begin to melt at a lower temperature.
Salt water has a lower freezing point and a higher boiling point.
True. Water has a lower melting point than most rocks, so when a rock is wet, the presence of water can lower the overall melting point of the rock.
