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.
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.
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.
yes as it is plastic
The specific heat capacity of ice is 2.09 J/g°C and the heat of fusion of ice is 334 J/g. To melt 2 kg of ice, you first need to heat the ice from -30°C to 0°C, then provide energy to melt the ice at 0°C. The total energy required is 9836 J + 66800 J = 76636 J.
The specific heat capacity of lead is 0.128 J/g°C. To calculate the heat energy required to melt the lead, you would first need to raise the temperature of the lead from 24°C to its melting point of 327.5°C using the equation Q = mcΔT. Then, once the lead is at its melting point, you would calculate the heat energy required to melt the lead using the equation Q = mL, where L is the heat of fusion for lead which is 23.5 kJ/kg.
A lot of heat
iron melts at 1536 °C
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.
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.
There are different kinds of sand, but one of the most common, quartz sand, has a specific heat of 830 (J/kg°C)
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.
