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
Heat because Ice and water would thaw out and begin to heat up
It would take approximately 334,000 Joules of heat to melt a 1 kg block of ice at 0 degrees Celsius. This energy is required to break the bonds holding the ice molecules together and transition from a solid to a liquid state, known as the heat of fusion.
The energy required to melt ice is known as the heat of fusion, which is about 334 joules per gram. Therefore, it would take approximately 3340 joules of energy to melt 10g of ice.
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.
The time to melt a block of ice depends on various factors such as temperature, heat source, and insulation. With a constant heat source, it could take several hours to a few days to melt a block of ice that size. The larger the surface area exposed to the heat source, the quicker the ice will melt.
The heat required to melt 2 kg of mercury can be calculated using its specific heat capacity (0.14 J/g°C) and its melting point (−38.83°C). The formula Q = mcΔT can be used to find the heat needed, where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.
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.
There are different kinds of sand, but one of the most common, quartz sand, has a specific heat of 830 (J/kg°C)
simply heat the solid.
ice actually melts pretty fast on aluminum, it will probably take 15 minutes
It really depends on the amount of chocolate you are trying to melt.
