How much heat energy would it take to melt a 20 kg block of lead that was at 24 degrees Celsius?
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.
How much heat is required to melt 68.5 g of ice at its melting point?
The heat required to melt ice at its melting point is known as the heat of fusion, which is 334 J/g. Therefore, the heat needed to melt 68.5 g of ice is 68.5 g x 334 J/g = 22,939 J.
How much heat does it take to melt 3 kg of helium?
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.
How much energy would be required to melt 32.0 g of ice?
The amount of energy required to melt ice can be calculated using the equation: energy = mass of ice * heat of fusion. The heat of fusion for ice is 334 J/g, so for 32.0 g of ice, the energy required would be 32.0 g * 334 J/g = 10,688 J.
How would you show that water is not a good conductor of heat?
A test tube is filled with tap water (about 25oC). An ice block is placed in the test tube and is kept at the bottom of the test tube by means of a wire gauze. Next (without delaying too much since the ice block would melt completely!), the test tube is bent and the upper end of the test tube placed in a Bunsen flame. It is found that the water at the upper end boils before the ice block melts. This shows that water is a poor conductor of heat.

How much heat does it take to melt bubble wrap?
A lot of heat
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
What is the measurement of how much heat energy is required for a substance to melt?
The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.
How much energy is required to melt 10g of ice?
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.
How much heat does it take to melt iron?
iron melts at 1536 °C
Which metals will melt when heated?
all of them, just depends on how much heat you use
How much heat (in kilocalories) is required to melt 1.95mol of solid acetic acid?
The heat of fusion for acetic acid is 20.5 kcal/mol. Therefore, the amount of heat required to melt 1.95 mol of solid acetic acid would be 1.95 mol x 20.5 kcal/mol = 40 kcal.
How much energy is required to melt 56g?
The energy required to melt a substance can be calculated using the formula: Energy = mass x heat of fusion. For water, the heat of fusion is 334 J/g. Therefore, the energy required to melt 56g of water would be 56g x 334 J/g = 18,704 J.
How much heat energy must be absorbed to completely melt 35 grams of h2o at o degrees?
it will be 11,700J since the formula would be: q=mHf=35g x 334 J/g= 11,700 J
How much heat is required to melt 68.5 g of ice at its melting point?
The heat required to melt ice at its melting point is known as the heat of fusion, which is 334 J/g. Therefore, the heat needed to melt 68.5 g of ice is 68.5 g x 334 J/g = 22,939 J.
How much heat is needed to melt 2.50 kg of water at its melting point?
The heat needed to melt a substance is given by the formula: Q = m * Lf, where Q is the heat, m is the mass, and Lf is the specific latent heat of fusion. For water, Lf is 334 kJ/kg. Plugging in the values, you would need 2.50 kg * 334 kJ/kg ≈ 835 kJ to melt 2.50 kg of water at its melting point.
