How much heat does it take to raise 1.0 kg of lead from 0 degree celsius to 90 degree celsius?
look up the specific heat capacity for lead.
Heat= mass*specificheat*(Tf-ti)
make certain mass is in the same units as the specific heat capacity is.

Calculate the heat of 5kg of lead [s.h.c of lead
To find out how much heat is required to raise the temperature of lead from 0 degree Celsius to 90 degree Celsius, we can use the formula:
Q = m * c * ΔT
Where:
Q is the amount of heat energy required
m is the mass of the substance (in this case, lead)
c is the specific heat capacity of the substance
ΔT is the change in temperature
For lead, the specific heat capacity (c) is approximately 128 J/kg·K.
Given that the mass of lead (m) is 1.0 kg and the temperature change (ΔT) is 90°C - 0°C = 90 K, we can substitute these values into the formula:
Q = 1.0 kg * 128 J/kg·K * 90 K
= 11520 J
Therefore, it takes approximately 11520 Joules of heat to raise 1.0 kg of lead from 0 degrees Celsius to 90 degrees Celsius.
