Calculate the wavenumber for O_H

Q = 44.9 j

Explanation:

Mass of iron = 5.0 g

Change in temperature = 20 °C

Specific heat of iron = 0.449 j/g.°C

Heat transferred = ?

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Solution:

Q = m.c. ΔT

Q = 5 g × 0.449 j/g.°C ×  20 °C

Q = 44.9 j
