Question

A 14.00-g piece of iron absorbs 1000 joules of heat energy, and its temperature changes from 25°C to 125°C. Calculate the specific heat capacity of iron.

Answer 1

THE SPECIFIC HEAT OF IRON IS 0.714 J/g °C

Step-by-step explanation:

Heat absorbed = 1000 J

Mass of the piece of iron = 14 g

Temeperature changes = ( 125-25)°C= 100°C

specific heat of iron = unknown

To find the specific heat of iron in the question use the formula of heat

Heat = mass * specific heat * temperature change

Specific heat = Heat / mass * temperature change

Specific heat = 1000 / 14 * 100

Specific heat = 1000 / 1400

Specific heat = 0.714 J/g °C

So therefore, the specific heat of iron is 0.714 J/g °C
