Hot material generally melts more readily than cold material.
does the melting point of a substance change over time
Yes and no. The shape can affect how efficiently the water is being heated and how efficiently the evaporated water can escape a vessel. An almost completely sealed water container will show very little signs of evaporation because any water that evaporates will soon condense back into the container. The evaporation is still happening, it's just not as observable or relevant because the evaporation cannot leave the system efficiently.
Yes the shape of ice does affect its melting time. if you took a liter of water and froze it into a sheet 1/2 a cm thick, and another liter of water and shape it into a ball, then placed both pieces of ice outside to melt, the sheet would melt before the ball,this is because the sheet has more surface area than the ball so heat from the outside can get into it faster.
The amount of water in a container will affect how fast it heats up. If there is a small amount of water in a container the water will biol/heat faster. However, if there is a big amount of water it will take longer for the heat to reach all parts of the water resulting in a longer time for the water to boil/heat
Trick question. AT palladium's melting point it exists both as a liquid and a solid. It is in equilibrium with both phases. Of course you'd have a hard time getting it to its precise melting point.
If the container is cold, then the ice cream will stay colder longer, therefore taking less time to melt. If the container is warm, the ice cream will get slightly warmer than if it was cold, which makes it take less time to melt.

This is called the melting point, and the temperature is different for every material. For pure water, it is zero degrees Celsius, or 32 degrees Fahrenheit. Determining the melting point of any material is an important clue to determining what the material is.

closer it is to base down the slower it melts, closer it is to base up the faster it melts.
The melting phase is a period in time where an object is melting but not completely melted.
5 factors that affect breaking time;- under the influence of alcohol- under the influence of drugs- reaction time- the friction of conditions and car- car material- speed- acceleration- thinking time
I think they are Parent material, Relief, Organisms, Climate, and Time.
yes because if milk gets warm the chocolate will melt by prema at kenmore south state school

soft drinks contains acid which dematerialises any materials over a period of time
