Before the ice melts, the temperature of the mixture typically remains relatively stable, often hovering around 0°C (32°F), as the ice absorbs heat from the surrounding liquid without a significant increase in temperature. Once the ice completely melts, the temperature of the mixture may begin to rise, depending on the initial temperature of the liquid and the amount of ice added. After the ice has melted, the temperature will adjust based on the heat exchange until it reaches a new equilibrium. Overall, the melting process helps maintain a cooler temperature until the ice is gone.
Tar melts in the sun because it is made up of a mixture of hydrocarbons that have low melting points. When exposed to the heat of the sun, the temperature of the tar increases, causing it to soften and eventually melt.
Carbon is commonly used to make iron melt by forming a eutectic mixture. This process is known as carburizing or carbonization of iron. The addition of carbon lowers the melting point of iron by forming a eutectic mixture near 1153°C (2107°F).
That depends on the metal: mercury is already liquid at room temperature, gallium will melt in your hand, many alloys will melt in hot water, but other metals do have to be heated to thousands of degrees before they melt.
Depending on the composite of the concrete material, it can melt at different temperatures. When concrete reaches a high enough temperature such as more than 1000 degrees Celsius, it can crumble like sugar.
No, MDMA does not melt. It is a solid crystal at room temperature.
The only things that won't melt at high temperature are those that decompose first. For instance, wood will burn long before it melts! Many many things decompose at high temperatures before they melt. If it doesn't decompose first, everything will eventually melt.
The salt-ice mixture melts faster because the mixture's melting point is lower than that of pure ice, which is characteristic of a mixture. So the mixture causes the ice to melt at lower temperatures than 0 oC or 32 oF.
Sugar may melt before it burns.
Quite often, the temperature doesn't change. For example: if you melt ice, you convert ice at 0 °C to water at 0°C. You need to put heat energy into the ice to melt it, but its temperature doesn't change. (The change of state itself requires energy - this is a type of potential energy.)
It depends on what the lamp is made of. Some materials don't melt, they decompose or burn before reaching their melting point.

Melting point s can be "sharp" where the phase change occurs at a particular temperature, or the solid may soften and then melt over a range of temperatures. Conventionally melting point refers to the sharp melting point, and this is exhibited by pure chemical compounds that do not decompose. Slip melting point usually refers to a technique for measuring the point at which a waxy solid "slips" in a tube -waxy solids such as hydrocarbons produced from petroleum oil are mixture and melt over a range and this is near reproducible way of obtaining a diagnostic single "melt" temperature for the mixture.
It does melt.

Yes you can melt it. But you want a high temperature.
Ice cube melts but the glacier does not melt because depending upon the temperature of the surrounding. When an ice cube is taken out of the refrigerator, there is a sudden change in the temperature of the surrounding as it (temperature) increases so the ice cube depending upon the temperate of the surroundings melts earlier. According to the latent heat of fusion, it will first melt completely to become liquid and then its temperature will increase to reach a state of thermal equilibrium e of the room temperature. In case of a glacier, the temperature of its surroundings is less so a glacier does not melt like ice cube.
