Answer 2

Calculating Heat Released During Crystallization of Lead Block

To calculate the heat released during the crystallization of a lead block, we can use the formula:

Q = m * L

Where: - Q = heat released (in joules) - m = mass of the substance (in grams) - L = heat of crystallization (in J/g)

Given: - m = 400 g - L = 24 J/g (heat of crystallization for lead)

Calculation

Using the formula Q = m * L, we can calculate the heat released during the crystallization of the lead block:

Q = 400 g * 24 J/g Q = 9600 J

Therefore, the amount of heat released during the crystallization of the lead block is 9600 joules.
