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.

What type of bone growth do you think a 40-year-old male experiences?
Vsevolod [243]

A 40-year-old male undergoes a type of bone growth known as appositional growth. This growth produces an increase in the diameter of bones.

Appositional growth is a type of bone growth caused by the addition of new bone tissue layers at the surface of the bones.

In appositional growth, the cartilage grows in its diameter by the addition of extracellular matrix on the peripheral cartilage surface.

During this process, cartilage-forming cells secrete more extracellular matrix against the external side of the cartilage tissue.
