Answer:

When 2.04g of lead is heat from 104 Kelvin to 204 Kelvin, there is 26.112 Joule generated.

Step-by-step explanation:

Step 1: Data given

2.04 grams of lead changes from 104 to 204 Kelvin

Step 2: Calculate the generated heat

Q = m*c*ΔT

with Q = Heat energy (in Joules)

with m = mass of a substance (kg)

with c = specific heat (in J/g*K)

with ΔT = Change in temperature = T2 - T1

In this case we have

Q = TO BE DETERMINED

m = 2.04 grams

c = specific heat of lead = 0.128J/ g*K

ΔT = 204 Kelvin - 104 Kelvin = 100

Q = 2.04g * 0.128 J/g*K * 100 K = 26.112 J

When 2.04g of lead is heat from 104 Kelvin to 204 Kelvin, there is 26.112 Joule generated.
