Question

(show all your works from part a to part d and please don't skip any questions. Thanks you)

a. define the term: specific heat capacity

b. list the equation that relates heat change to mass, specific heat and the change in temperature

c. the specific heat capacity of copper is 0.387 J/g-C. How many calories of heat are required to increase the temperature of 52.0g of copper metal from 25.2 degree celsius to 80.8  degree celsius?

d. the specific heat capacity of water is 4.184 J/g-C. How many calories of heat are required to increase the temperature of 52.0g of water from 80.8 degree celsius to 25.2 degree celsius?

Explanation / Answer

The amount of heat required to rise the temperature one degree celcius of one gram of the substance.
Q = m * S * dT
Q = heat energy
m = mass of the substance
S = specific heat capacity
dT = change in temperature
q = 52 * 0.387 *(80.8 - 25.2)
q = 1.118 kJ
q = m * s * dT
q = 52 * 4.184 * (80.8 - 25.2)
q = 12.096 kJ
