Are you familiar with the the idea of specific heat? If not, Google for "specific heat".Bruce Haawkins said:ok them how do I work out how much energy it takes to get 1 kg of lead to a given temprature from 0 kelvin

The energy required to heat a substance can be calculated using the specific heat capacity and the change in temperature. For lead, the specific heat capacity is 128 J/kg*K, so the energy required to heat 1 kg of lead to a given temperature can be calculated using the formula Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.
The amount of energy required to heat 1 kg of lead to a specific temperature will depend on the specific heat capacity of lead and the change in temperature. Using the formula Q = mcΔT, the energy can be calculated.
The specific heat capacity of lead is 128 J/kg*K. This means that 128 Joules of energy is required to raise the temperature of 1 kg of lead by 1 Kelvin.
The energy required to heat lead is relatively high compared to other substances. For example, the specific heat capacity of water is 4181 J/kg*K, which is over 30 times higher than lead. This means that it takes much more energy to heat water compared to lead.
Yes, the energy required to heat lead can be reduced by using insulation to prevent heat loss. This will reduce the amount of energy needed to reach a specific temperature. Additionally, using a more efficient heating method, such as induction heating, can also reduce the energy required.
