The specific heat capacity of copper is 0.092 calories per gram per degree Celsius. How much heat is required to raise the temperature of a 9 g piece of copper from 0°C to 100°C?

Answer : The amount of heat required is, 82.8 cal

Explanation :

Formula used :

where,

q = heat required = ?

m = mass of copper = 9 g

c = specific heat of copper =

= final temperature =

= initial temperature =

Now put all the given values in the above formula, we get:

Thus, the amount of heat required is, 82.8 cal

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
