To melt 60 lbs of lead, approximately 25,200 BTU of heat energy is required. Lead has a melting point of 621.5°F and a specific heat capacity of 0.031 BTU/lb°F. Multiplying these values gives the total heat energy needed for melting.
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.
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.
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.

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.
They take them apart and then melt down the parts for lead and copper.
1 60lbs bag makes around a 1' by 1' by 3" thick pad..
have him gain a LOT of weight and take him to a doctor. Definitely take him to a doctor for diagnosis and an eating plan.

glaciers are big and vary cold.
That depends on the amount of ice and the ambient temperature of its surroundings.
it takes 2 minutes for it to melt
At 70 degrees it would take 24 hours to melt 2000 lbs of ice
I't will take about 5 seconds because snow is water.
