iron melts at 1536 °C
A lot of heat
it depends on the units of the specific heat, but if they are J / goC then you would take your delta T (25-20) and multiply it by your mass (14g) and multiply by your specific heat. In this case it would be 5 * 14 * .11 = 7.7 (with whatever units of energy your specific heat is in.) Just make sure your units cancel out and you will get it right!
One is the temperature of the water could be warmerSecondly when an ice cube is in water, conduction takes place. The kinetic energy of the water particles more time.moves to the ice causing it to melt. When in air radiation or convection must take place which will take
It depends on the manufacture of the device. High quality gas powered ones can heat up in seconds. Cheap mains powered ones can take up to 5 minutes.
The melting point of the ingredients in your drinks have different values, water tends to be the last part of a drink or drinks to melt. For example Orange juice will start to melt before pure water, because it has started to melt first it has the abilty to take in more heat over a lesser surface area and the liquid will help it to melt faster as well.
A lot of heat
63 kJ is needed.
Heat because Ice and water would thaw out and begin to heat up
1,277,800 j
To know how fast this will melt you need to know the amount of stainless steel and the temperature of the stainless steel at the beginning. Then using the formulas of energy needed to heat it (Cp, I think) and melt it (enthalpy) you can calculate when it will melt.
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 (:
Iron would definitely still be a solid. Water begins to boil at only 100 degrees celsius so there for it would take a much higher temperature to even begin to melt iron.
simply heat the solid.
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.
