Constant

Question 5

The ______ of ______ of a substance is the amount of energy released or absorbed when it changes from a liquid to solid, or from a solid to a liquid.

Answer 5

Heat of fusion

Question 6

Q = mc🔺t

What are the variables?

Answer 6

Q = thermal energy (J)
m = mass (g)
c = specific heat capacity (J/g°C)
🔺t = change in temperature (°C)

Question 7

H(fus) = Q/n

What are the variables?

Answer 7

H(fus) = heat of fusion (KJ/mol)
Q = thermal energy (KJ)
n = # of moles of substance (mol)

Question 8

n = m/M

What are the variables?

Answer 8

n = # of moles of substance (mol)
m = mass (g)
M = molar mass (g/mol)

Question 9

The ______ of ______ of a substance is the amount of energy released or absorbed when it changes from a gas to a liquid, or from a liquid to a gas.

Answer 9

Heat of vaporization

Question 10

H(vap) = Q/n

What are the variables?

Answer 10

H(vap) = heat of vaporization (KJ/mol)
Q = thermal energy (KJ)
n = # of moles of substance (mol)
