The specific heat of iron is 0.11 cal/goC. A cafeteria fork made of iron has a mass of 20 grams. How much heat energy is needed

Natasha2012 [34]

Hello!

To solve this problem you need to use the following equation for heat transfer to calculate the heat added (Q) and substitute in this equation the values for specific heat (c), mass (m) and temperature difference (ΔT). The following equation describes the heat needed to raise the temperature of a given object:

$Q=c*m*ΔT=(0,11cal/g°C)*(11g)*(75°C-25°C)=121 cal$ :

So, to heat the cafeteria fork made of iron with a mass of 20 grams from 25 °C to 75°C, you'll need 121 cal of heat energy.

Chocolate and other sweets are also great sources of carbohydrates. </span>
