Final answer:
To find out the heat required to increase the temperature of lead, use the heat formula Q = m × ΔT × c, inserting the mass of lead, temperature change, and lead's specific heat capacity.
Step-by-step explanation:
To calculate how many joules of heat are required to heat 65g of lead from 22.0°C to 98.5°C, we use the formula Q = m × ΔT × c, where Q is the heat in joules, m is the mass in grams, ΔT is the change in temperature in degrees Celsius, and c is the specific heat capacity of the material in J/g°C.
As the specific heat of lead is not provided in the options, the correct formula would need to use the specific heat capacity for lead (which is approximately 0.128 J/g°C). None of the provided options contain the correct specific heat capacity for lead. Therefore, the correct calculation would be:
Q = (65 g) × (98.5°C - 22.0°C) × specific heat of lead
The specific heat of lead should be used for the calculation, not the values provided in options B and D.
