Answer: The amount of energy required to raise the given amount of temperature is 6400 J

Explanation:

To calculate the heat absorbed by the lead, we use the equation:

[tex]q=mc\Delta T[/tex]

where,

q = heat absorbed

m = mass of lead = 200 g

c = heat capacity of lead = 0.128 J/g°C

[tex]\Delta T[/tex] = change in temperature = 250°C

Putting values in above equation, we get:

[tex]q=200g\times 0.128J/g^oC\times 250^oC=6400J[/tex]

Hence, the amount of energy required to raise the given amount of temperature is 6400 J
