10.4 Heating Curves and Heat Capacity

Question 1

heat capacity (Cp)

Answer 1

the energy required to raise the temperature of an object by 1 degree C at constant pressure

Question 2

specific heat (cs)

Answer 2

the energy required to raise the temperature of 1 g of a substance by 1 degree celsius at constant pressure

Question 3

melting point of water

Answer 3

0 degree celsius (heat of fusion)

Question 4

boiling point of water

Answer 4

100 degrees celsius (heat of vaporization)

Question 5

while one phase changes to another, the temperature

Answer 5

remains contact as heat energy is used to break bonds

Question 6

straight parts represent what

Answer 6

two phases in equilibrium when bonds are breaking to move to next phase

Question 7

molar heat capacity

Answer 7

is the amount of heat required to raise the temperature of one mole of a substance by one degree Celsius (or one Kelvin). It is expressed in units of J/(mol·K).

Question 8

how to calculate heat transferred based based on temp, material, heat capacity

Answer 8

q=m(mass)•C(specific heat capacity)•delta T(change in temp)
