How much heat does it take to melt 3 kg of helium?
63 kJ is needed.
How much heat energy would it take to melt a 20 kg block of lead that was at 24 degrees Celsius?
1,277,800 j
Does the size of ice affect its melting time?
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.
Does plastic heat up?
yes as it is plastic
Why do mercury expand when heated?
When you heat a material, you cause the molecules to vibrate with more kinetic energy. So think of the mercury as a group of people standing as close to each other as possible. If you add heat to this group (which can be represented by the people starting to wiggle their bodies and flail their arms) the group will start to take up more and more space depending on how much extra wiggling they do. This is a good comparison to the molecules of mercury. As they are heated, they vibrate with larger oscillations. This will mean they need more room to "wiggle", hence the mercury will expand.
How much heat does it take to melt bubble wrap?
A lot of heat
Does it take more heat to melt 12 grams of CH4 or 12 grams of Hg?
At room temperature, mercury (Hg) is a liquid, and methane (CH4) is a gas. The melting point of methane is -182.5 degrees Celsius. The melting point of mercury is -39 degrees Celsius. It takes more heat to melt the mercury.
How much heat does it take to melt iron?
iron melts at 1536 °C
How much heat does it take to melt 3 kg of helium?
63 kJ is needed.
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
How much heat energy would it take to melt a 20 kg block of lead that was at 24 degrees Celsius?
1,277,800 j
Average time to melt milk chocolate?
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.
How much heat does it take to melt sand?
There are different kinds of sand, but one of the most common, quartz sand, has a specific heat of 830 (J/kg°C)
How long does it take a one pound block of ice to melt?
It depends on how hot you heat it (:
How long does it take to melt pure silica?
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.
How long does it take to melt chocolate?
It really depends on the amount of chocolate you are trying to melt.
Does it take more heat to vaporize 12 grams of CH4 or 12 grams of Hg?
It takes more heat to melt 12.0 grams of Hg.
