Question

You decide to make a copper bracelet for your friend. In order to do this you need to heat 29.2g of copper from 25 C to 275 C. Calculate the amount of heat te quieted feo this reaction to proceed.

Answer 1

Amount of heat required = 2810.5 J

Step-by-step explanation:

Given data:

Mass of copper = 29.2 g

Initial temperature = 25°C

Final temperature = 275°C

Amount of heat required = ?

Solution:

Specific heat capacity of copper is 0.385 j/g.°C.

Formula:

Q = m×c×ΔT

ΔT = 275°C - 25°C

ΔT = 250°C

Q = 29.2 g × 0.385 j/g.°C ×250°C

Q = 2810.5 J
