Because the larger the piece of ice is, the longer it will take for heat to melt it. I smaller piece of ice has fewer layers that heat needs to penetrate to melt it compare to a larger piece of ice.
yes as it is plastic
I assume you mean "iceberg". If they are large, they will take a long time to melt, since they can only melt at their surface.The time it takes them to melt will also depend on the temperature - as well as the shape of the iceberg.
Argon is sort of the opposite to "Helium" because when you take in Helium it makes your voice go high and squeeky but once you take in Argon it makes your voice Low and manly! Hope this helped
To melt helium, it requires extremely low temperatures rather than heat. Helium becomes a liquid at temperatures below -268 degrees Celsius (-450 degrees Fahrenheit) and does not require significant amounts of heat to transition from its gaseous state to a liquid state.
A lot of heat
iron melts at 1536 °C
Heat because Ice and water would thaw out and begin to heat up

It varies based on how you melt it and how much chocolate you are melting with what heat amount. In the microwave, it will take 2 to 3 minutes (stirring at 30 second intervals). In a double-boiler method over medium-high heat, it should take 5 to 10 minutes.
There are different kinds of sand, but one of the most common, quartz sand, has a specific heat of 830 (J/kg°C)
It depends on how hot you heat it (:
Helium plus released energy (heat)
It takes about 3,100 degrees feirenheit to melt pure silica Pure silica (SiO2) has a "glass melting point"- at a viscosity of 10 Pa·s (100 P)- of over 2300 °C (4200 °F). The amount of time it would take to melt would depend on how much heat you applied.
It really depends on the amount of chocolate you are trying to melt.
It takes more heat to melt 12.0 grams of Hg.
