0.95 K (-272.20° C, -457.96° F) at a pressure of 2.5 MPa
Heat because Ice and water would thaw out and begin to heat up
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.
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.
There are different kinds of sand, but one of the most common, quartz sand, has a specific heat of 830 (J/kg°C)
The time it takes for a one pound block of ice to melt depends on the temperature of its surroundings and the rate of heat transfer. In general, it can take anywhere from 45 minutes to a couple of hours for a one pound block of ice to melt at room temperature.
Helium is a gas at room temperature and pressure, so it does not melt. Instead, it turns into a liquid at extremely low temperatures (-268.9°C or -452°F). The amount of heat required to liquefy 3 kg of helium would depend on how much of it is in gas form and the specific heat capacity of helium at that temperature.
A lot of heat
iron melts at 1536 °C

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.

ice actually melts pretty fast on aluminum, it will probably take 15 minutes
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.
