Which substance melts ice better salt sugar or chalk?
i tried it and salt melts ice better than the other does anyone gonna answer me
What substances melts at 0 degrees Celsius?
Water melts at 0 degrees Celsius.
What melts ice faster salt sugar or chalk?
Salt melts ice faster than sugar and chalk because salt lowers the freezing point of water. When salt is added to ice, it disrupts the balance between the solid and liquid states, causing the ice to melt more quickly. Sugar and chalk do not have the same effect on lowering the freezing point of water.
What melts ice better chalk salt or sugar and why?
Salt melts ice better than chalk or sugar. Salt lowers the freezing point of water, causing ice to melt. Chalk does not have any properties that make it effective in melting ice, while sugar does not lower the freezing point as effectively as salt.
What can be used to separate iron from other substances?
Thermite, the iron melts.
What happen when you put chalk into water more then a week?
When chalk is submerged in water for more than a week, it may start to disintegrate and break apart due to the exposure to moisture. The water will gradually dissolve the calcium carbonate in the chalk, causing it to lose its integrity and crumble over time.
What factors contribute to the rate at which ice melts, as explored in the research paper on what makes ice melt faster?
The rate at which ice melts is influenced by factors such as temperature, surface area, and presence of substances like salt or sugar. These factors affect the energy transfer and molecular movement in the ice, leading to faster or slower melting.
What physical properties could you use to tell the difference between chalk and snow?
Snow is cold Chalk tastes bad.
What solid substance never melts?
No solid substance exists that never melts. All substances have a melting point at which they transition from a solid to a liquid state due to changes in temperature.
What forms when rock melts?
When rock melts, it forms magma. Magma is a molten mixture of rock-forming substances, gases, and water that is found beneath the Earth's surface. If the magma reaches the surface, it can then solidify to form igneous rocks.
What melts at lower temperatures diamond salt silver?
Salt (sodium chloride) is melted at 801 oC.
What is the melting point for chalk?
There are two types of chalk, calcium sulfate and calcium carbonate.The natural occurring sedimentary rock called chalk is a form of limestone made of the compound calcium carbonate. One of the crystal forms is calcite, which the melting point is 1,339 °C (2,442 °F; 1,612 K). The melting point of a second crystal form, aragonite, is 825 °C (1517 °F; 1,098 K).Blackboard chalk is made of calcium sulfate, also known as gypsum. The melting point is 1,460 °C (2,660 °F; 1,730 K),
