Question

How many joules of energy are needed to warm 5.00 g of silver from 25.0°C to 27.5°C? (The specific heat of silver is 0.24 J/g°C.)

Answer 1

Answer:

3J

Explanation:

The following were obtained from the question:

M = 5g

T1 = 25.0°C

T2 = 27.5°C

C = 0.24 J/g°C

Q=?

Using the following equation Q = MCΔT to solve for the energy need, we have:

Q = MCΔT

Q = 5 x 0.24 x (27.5 — 25)

Q = 5 x 0.24 x 2.5

Q = 3J
