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.
Why do iceburges take long to melt?
I assume you mean "iceberg". If they are large, they will take a long time to melt, since they can only melt at their surface.The time it takes them to melt will also depend on the temperature - as well as the shape of the iceberg.
How long does an ice cube take to melt?
The time it takes for an ice cube to melt can vary depending on factors such as the temperature of its surroundings, the size of the ice cube, and the material it is made from. On average, a small ice cube in a room temperature environment may take around 5-10 minutes to melt completely.
How much energy is required to melt 1.5 kg of lead?
36.8 kj
How long does ice take to melt when salt is added?
When salt is added to ice, it melts faster than without salt because salt lowers the freezing point of water. This means that the ice will melt more quickly when salt is present.
